Hi

I have Windows 2012 server DC, witch is also client acces point for exchange 2013.

The machine has two ip addressen 172.32.2.1 and 172.32.2.11 on the same interface,  i don''t want the 172.32.2.11 to be registerd in dns. Because this ip is not reacebol from a difrent site. How can prevent registeration of this ip.

Hope some knows the answer?



With kind regards, Bas van den Dikkenberg

I thing that the Active Directory was corrupted, but I don't know how happend it.

Chinese user names in Active Directory

$

Perhaps some Chinese speakers could help me out with this question.

Our current naming standard uses the initial letter of the first name and the entire last name, so for "Winston Churchill" you would have:

wchurchill

We will soon have a number of users with Chinese names. I believe first name last name order is reversed in Chinese.

Using another government official example, what would be the user name for "Hu Jintao" (with our current naming protocol)???

huj

???

Are there any Chinese AD admins who could advise me on this?

What's the preferred way to do this?


Please mark as helpful if you find my contribution useful or as an answer if it does answer your question. That will encourage me - and others - to take time out to help you.

hello all I thought this would be an easy google search and set somewhere in the end users a/d account. basically I am testing a password reminder policy. and want to set my test account password to expire in x amount of days. there is already a group policy for p/w to expire in 45 days. I have a reminder policy set for 7 days but of course I want to test it and I dont want to wait 45 days to test, can I change time on pc or something there has to be somewhere in a/d or something.

any advantage is separate AD sites for co-located child domains?

$
0

I inherited management of an AD forest some time ago, and as there were never any issues with authentication or other AD-dependent services (which weren't operator error), I never made any changes.  The site arrangement is now in flux as we're migrating out of one of our data centers.

We have multiple child domains off the forest root.  They're all co-located physically in the same site, and will be moving forward, with the root domain.  The previous administrator set up separate AD sites for each child domain.  The child domains have their own subnets, and these are associated with the domain-specific sites.

In other words, we have these AD sites:

Location1-rootDomain

Location1-ChildDomain1

Location1-ChildDomain2

Location2-rootDomain

Location2-ChildDomain1

and so forth.  I believe the thinking was this was somehow supposed to prevent root clients from authenticating against child DCs, or something.  I really don't see the purpose.  I only see it as unnecessarily delaying replication among different-domain DCs in the same physical location.

Is there any valid reason not to consolidate AD sites and put all the DCs in the same location in the same AD site?  We only do TS licensing in the root domain, and we don't have software dependent on site (aside from Exchange, where nothing will be moving anyway).

do you need to define an AD Site if there is no DC in that site?

refering to the MS article here: technet.microsoft.com/en-us/library/cc782048(WS.10).aspx

i note that defining AD sites assist with Replication, Authentication, and Active Directory-enabled services

If for example you have a geographically seperate branch office (connected by a high bandwidth WAN link 10MB) that also has it's own unique IP subnet in the corporate network, and that office is very small in terms of users (<5 users) and the only equipment onsite are the users PCs (ie no other servers onsite) - then is it better off in a design philosophy to NOT define that AD site in AD Sites and Services?

ie my understanding is that when the workstations attempt to log into the domain, the DNS server responds to the workstation by assigning it a Domain Controller to register to. It is the DNS server which determines which DC the workstation should register to - and it does this by determining the lowest cost path from workstation to it's nearest DC. assuming this is done for AD via the sites and site-links defined in AD Sites and Services...if there is no site for this branch office, then how does the DNS server know which is the lowest-cost DC to this workstation?


is this correct?

or should I define the branch office in AD Sites and Services anyway, regardless that there is no DC onsite?

comments/suggestions?

Set-ADDefaultDomainPasswordPolicy minimum password length above 16 2008 r2

Hello we are running a 2008 r2 domain at 2008 r2 functionality. If we use 

Set-ADDefaultDomainPasswordPolicy to set the minimum password length to 16 and works. Is this ok if by default you can only change it to 14

characters? It does show up in gui for the default domain group policy  correctly with 16 characters..

Thanks

Hi All,

I have around 350 AD 2008 R2 servers in my environment which are in different physical locations, all the active directory servers are working fine, but there is only one RODC server which is causing alot of 445 and 139 port traffic from different AD sites, there is only one subnet mapped to this AD Site, I have observed that there are many \PIPE\smar open sessions, i have googled alot but could not find a solution for this issue, even though i have recreated a new RODC but still the same problem exists.

Following links have been already followed but they all are for 2000 and NT environment:

I would highly appreciate if someone would assist me in solving this issue.

ADFS through TMG. Relying party trust certificate keeps giving me errors

$

Hello all,

I'm trying to use ADFS as a brand new install to authenticate us to our webscanning provider. I have setup ADFS with a relying party trust and I can access my xml path using

https://myserver.domain.com/adfs/ls/federationserverservice.asmx

this displays my xml file as it should. I've got this running internally and then published through TMG in our DMZ. I've setup TMG with the correct copies of the certificate and everything seems fine. I've also followed the setup of the relying party trust to the letter. However, when I try an authentication effort using their software I get the generic 'there was a problem accessing the site. try to browse the site again, if the problem persists' etc etc.

I take a look on my event log for ADFS and I've turned tracing on. What's happening is that the relying party trust certificate I installed (and is marked as 'this certificate is OK' is continually spitting out the following errors below.

I do know that the certificate is actually good, but something is going strange here with the CRL. This certificate for the relying party trust was NOT imported to my TMG box at all (because I find no articles anywhere that suggests it should be). I have also not imported my token signing certificate for the same reason. The web server certificate itself of the ADFS box has been added to TMG and when I access the ADFS xml path it reports as having a signed cert, so I presume that is OK.

A certificate used while validating the token is invalid.

Exception details:

MSIS3015: The signing certificate of the claims provider trust 'zscaler.net' identified by thumbprint 'FED50D8B82FBCA3F37823704BD2D46D08909D7F6' is not valid. It might indicate that the certificate has been revoked, has expired, or that the certificate chain is not trusted.

followed by

Microsoft.IdentityServer.Service.SecurityTokenService.RevocationValidationException: MSIS3015: The signing certificate of the claims provider trust 'zscaler.net' identified by thumbprint 'FED50D8B82FBCA3F37823704BD2D46D08909D7F6' is not valid. It might indicate that the certificate has been revoked, has expired, or that the certificate chain is not trusted.

Any help would be great, I'm going crazy staring at this now.

Event ID 2105 MSExchange ADAccess

Hello all,

I've originally posted this in the Exchange 2007 forum and it was suggest I post here instead:

Recently strted with these event ID 2105's on my front end exchange 2007 servers in an NLB cluster.  Any ideas?

Process MSEXCHANGEOWAAPPPOOL.CONFIG" -W "" -M 1 (PID=4496). Exchange Active Directory Provider failed to obtain DNS records for domain domain.co.uk. DNS Priority and Weight for the Domain Controllers in this domain will be set to the default values 0 (priority) and 100 (weight).

Exchange is working fine so I'm not sure what's happened.  The error suggests DNS but I can't see any issues there.

Any ideas?

DFSR issue

$

0

Hi,

I am having replication issue with Sysvol not getting replicated between AD Servers. I have 2 Windows 2008R2DNS/DHCP Servers. I ran dcdiag and I found that I have DFSR issue.

Starting test: VerifyEnterpriseReferences

         The following problems were found while verifying various important DN references. Note, that  these problems can be reported because of latency in replication.  So follow up to resolve the following problems, only if the same problem is reported on all DCs for a given domain or if  the problem persists after replication has had reasonable time to replicate changes.

[1] Problem: Missing Expected Value

Base Object:

CN=RA,CN=Topology,CN=Domain System Volume,CN=DFSR-

GlobalSettings,CN=System,DC=office,DC=apption,DC=com

Base Object Description: "SYSVOL FRS Member Object"

Value Object Attribute Name: serverReference

Value Object Description: "DC Account Object"

Recommended Action: Check if this server is deleted, and if so clean up this DCs SYSVOL FRS Member Object.  Also see Knowledge Base Article:  Q312862

I found this link from the Q312862 http://technet.microsoft.com/en-us/library/cc794759(WS.10).aspx and notice that under the MyDomain\System\File Replication Service I have no Servers in the right pane. Also under MyDomain\DFRS-GlobalSettings\Domain System Volume\Topology I have 3 Servers listed. One being the "RA" that is from the error above.

How should I proceed in fixing this problem?

Thank you

Can't join domain from different subnet

$

Hi,

 

I'm unable to join a domain from a different subnet with the following setup:

Active directory with DNS installed. DNS Server for the AD server points to itself (not loopback, but actual ip).

There are no firewalls activated on the client or the AD server. 

Dns for the client on the different subnet (windows 7 pro) that's unable to join is set to the IP of the AD server.

I'm getting the following error:

 

The error was: "This operation returned because the timeout period expired."

(error code 0x000005B4 ERROR_TIMEOUT)

 

I'm unable to ping the domain name, nor do a nslookup (it times out). 

If i try the above steps from the same subnet, everything works fine.

 

Am I missing something here? 

 

Thanks

-Kjartan

 

AD accounts that have been set up to never expire are expiring

Hi,

We have a mix of 2003/2008 R2 DC's. We are experiencing the following issue :

AD accounts that have been set up to never expire are expiring. Seems that users were contractors now permanent or are contractors. When looking at these accounts on the "account" tab on AD the account is showing to expire on the 24/1/2013 Although expiry is ticked to "never" and the date is greyed out, it seems as though it has still
used this date to expire. Users are getting an error message when logging into the PC "Account has expired".

Replication Errors

Okay, here is my issue. I have a root domain(a) and a child domain(b). W2k3...Three sites with a DC in each site per domain. In Oct. we moved datacenters and shutdown the servers(vm's) but didn't bring them up until Jan. Then getting the network issues hammered out it went until mid Jan. This week I tried to upgrade to w2k8 and had no problem prepping the forest and the domain but had an issue trying to add a DC that I have taken out of AD last week(had to seize the role..pdc emulator after it wouldnt play nice). It started to say access denied and target account name is incorrect. One thing has led to another and I have seen that replication is broken and stuff has been tombstoned and errors fill up my logs. Just as I get replication working it fails again. What should I do when it comes to solving this issue. Or a better question is how do I isolate one problem without bringing my entire infrastructure down...Any suggestions...
