I did post this some time ago, but the problem is still occuring.
We're seeing a strange problem .... SBS 2003 r2 approx 10 XP Pro clients.
They have applications that look at Netbios names to run... eg. sage etc.
they look for \\sbs .
They work fine for hours and then all of a sudden they stop, and if you do
\\sbs to see the shares all it shows is the offline redirected my documents.
If you do \\sbs.domain.local then they sometimes appear, but often it fails.
It takes a reboot of the server AND the workstations to get everything
working again.
Have run dcdiag and netdiag and it passes all tests except that Messenger
service isnt running.
I've tried an entry for the server in the hosts file but that doesn't help.
Clients are all dhcp node type 0x8 which I believe is hybrid. WINS/NBNS and
DNS Server ip's are handed out over dhcp too.
This is causing major pain for my customer so any help is greatly appreciated.
Follow up on this...
Last week we fitted a new NIC and it was ok until this morning... about 6
days.... then the problem reappeared....
What we're also seeing now is that even trying \\sbs.domain.local , ie. dns
name is not finding the shares either. However if you ping with \\sbs or
\\sbs.domain.local it finds the ip and responds even after an ipconfig
/flushdns.
It does sound very similar to
http://blogs.technet.com/sbs/archive/2008/01/30/sbs-clients-lose-access-to-shares-and-or-cannot-get-dhcp-addresses.aspx
but the Symantec s/w is DEFINATELY NOT installed, so its not that, though
the problem seems very similar.
The NBTSTAT -A is the same from a client when it's all fine AND when they
have the problem.
Theres nothing in the event logs that would indicate the source of the
problem.
Thanks once again for all your help.
