Windows XP pro losing domain access

[paddy138]

Has anyone seen Windows XP systems lose their domain membership?

WinNT 4.0 domain, WinXP Pro workstations. W2K DNS servers. Migrated from NT 4.0 domain to AD on W2K. Changed the zone settings on the DNS server to be AD Integrated. Changed the DNS settings through DHCP to auto-register the hosts to DNS.
Workstations on the same LAN as the domain controllers (2) get in fine. Remote sites (over various sized WAN links, no remote domain controllers); users were not logging into the domain.
On some workstations, removing the system from the domain (locally on the workstation and in the domain) and adding it back in fixed it.
On a few workstations (no real difference in systems; over various connections) the systems are receiving this error message in the Event Log
Source:Userenv
Event ID: 1000
Windows cannot obtain the domain controller name for your computer network.

Ping the DC and it never times-out (round-trip time varies, but never dies).

1) Has anyone seen this?
2) Any ideas on how to fix it?

. Make sure the DNS entry points to your DNS servers or the DC and not your ISP's DNS servers.

. In intractible cases, create a LMHOSTS file and make a "1b" Domain PRE entry for the DC. Remember the Netbio name entry must be padded to 15 places. See:
