RE: [ActiveDir] GC availability issue?

[Tony Murray]

Hi Jeremy   The problem with machines contacting DCs in other sites could be related to your subnet definitions in AD.  Check to see that all subnets are registered in AD and are associated with the appropriate site.   Also check your DNS settings, especially on the machines displaying the problem.   While your problems don’t sound like they could be related to the number of GCs, you should perhaps consider why you only have 2 out of a possible 5.  Is there any reason why you could not make all of your DCs GCs?      Tony   From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Burkes, Jeremy [Contractor] Sent: Tuesday, 19 July 2005 6:34 a.m. To: ActiveDir@mail.activedir.org Subject: [ActiveDir] GC availability issue?   Everyone,             We have an empty root domain and a child domain with approximately 9 or so sites in the forest.  The root domain has 2 DCs (1 GC) and the child domain has 3 DCs (1GC) both of which are located in our main site.  At our main site where I am located we have approximately 500 users.  The best scenario I can give you is we do PC rollouts where we take a large number of PCs 30-50 at a time and rename them with an old extension in the host name then we bring a new machine onto the network with the same name.  Sometimes we get an error saying the computer account already exists in the organization when we try to name the new machine with the same name, but the issue is inconsistent.  I did some traffic sniffing with a PC and found that approximately 50% of the time machines in our site are contacting servers in other site for directory service information instead of our site DCs.  Even machines that have been on the network are not using local site DCs for information all the time but using other site DCs instead.  I am wondering what could be causing this.  This configuration has been static for sometime nothing new has been introduced except for Windows 2003 schema (could this be the cause?).  I think it is because we do not have enough GCs in our site (2), but my boss disagrees.  What does everyone think?   Jeremy ------------------------------------------------------------------- Jeremy Burkes Strategic Systems Programs Management Information Systems Help Desk: 202-764-1442        Work: 202-764-1270 |         Fax: 202-764-1503 [EMAIL PROTECTED]   This e-mail message has been scanned for Viruses and Content and cleared by NetIQ MailMarshal at Gen-i Limited
