"special" server causing slow login with netbios

J

Jerry Bogren

Network configured like this:

W2K dhcp server provides wins and dns data to client
machines at startup.

AD installed on domain controllers

multiple vlans ( hence WINS and NETBios)

DNS list consists of 6 servers ( 2 internal and 4
external)

Network sniffing shows the slow down is caused by a DNS
search for a server named SPECIAL. This appears to be a
NetBios Name Server (NBNS from the sniffer data)

It goes to each DNS server in the DNS List and searches
for this list of servers;

First DNS server (.ww.xx.yy.zz is the State's domain name
for us)
Special.ww.xx.yy.zz
Special.xx.yy.zz
Special.yy.zz
Special.zz

Goes on to repeat this at all 6 DNS servers.

If we shut off netbios - the search goes away.

Client machines are XP or W2k - both fully patched.

Any Ideas

It sounds like a persistent mapped drive, startup application, or startup/logon/user
script, is referring to that server by name. Check Event Viewer to see if any errors
give a clue. Also try booting into safe mode with networking to see if logon
improves. If it does you have a startup application/service referring to than name
and you can use msconfig to troubleshoot via selective startup. Autoruns from
SysInternals is free and gives extensive info on startup processes. --- Steve

Thanks Steve!
No mapped Drives
No login scripts
