I believe Windows 2000 and Windows XP will attach their own domain name suffix to search for the host in DNS. For example if you give hostname and the workstation's domain name is domain.com it will try hostname.domain.com to see if it can resolve it in DNS. The search order for Windows 2000 and XP clients I believe is:

If the client is specifying \\hostname and there is no DNS search suffix set then I believe it will use WINS for name resolution. I could be wrong, but that's my understanding.

There is no way (that I know of) where they would try WINS first. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Rimmerman, Russ Sent: Tuesday, October 05, 2004 11:25 AM To: '[EMAIL PROTECTED]' Subject: RE: [ActiveDir] WAN outage caused issues... How would I know if their drive mappings are using WINS names and not DNS names? \\hostname vs \\hostname.domain.com? -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Renouf, Phil Sent: Tuesday, October 05, 2004 10:51 AM To: [EMAIL PROTECTED] Subject: RE: [ActiveDir] WAN outage caused issues... If they are using WINS for resolution then yes it could be their issue. If their drive mappings are using WINS names and not DNS names then that would make sense as to why they couldn't map them. I assume they were still able to log on an resolve the DC?

No, the site and subnet is defined properly, they're all using their local DC. All users at the remote site had issues. They're using their DC for DNS, and going back to HeadQuarters for WINS. Could the WINS be the issue? They couldn't contact WINS because the WAN link outage, that's for sure. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Mulnick, Al Sent: Tuesday, October 05, 2004 10:37 AM To: '[EMAIL PROTECTED]' Subject: RE: [ActiveDir] WAN outage caused issues... Were the clients trying to use the remote DCs when they shouldn't be? What was the scope of the problem? Was it all users or just a few users in the site? -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Rimmerman, Russ Sent: Tuesday, October 05, 2004 11:34 AM To: '[EMAIL PROTECTED]' Subject: RE: [ActiveDir] WAN outage caused issues... Yes, all our domain controllers are also DNS servers. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Robert Rutherford Sent: Tuesday, October 05, 2004 10:30 AM To: [EMAIL PROTECTED] Subject: RE: [ActiveDir] WAN outage caused issues... Has the remote site got its own DNS server? -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Rimmerman, Russ Sent: 05 October 2004 16:27 To: '[EMAIL PROTECTED]' Subject: [ActiveDir] WAN outage caused issues... What's the deal on WAN links going down between AD sites? As long as each site has a Global Catalog, they should be fine, correct? We had a remote site's WAN link go down the other day, and users eventually could not access any network drives (on the local file server even). They rebooted and it took forever to get the ctrl-alt-del logon box too. They couldn't get any network resources at all, just local drives and printers. We're in an Win2k AD domain with SP4. Most of the clients are XP and some are Win2k.
