Slow startup with Domain Account - Trying to resolve WPAD address?
Posted on 2011-03-23
Hey Experts, I'm working with a XP pro notebook that has been run as a workgroup machine for a long time and has recently been joined to the company domain. When logging into the user's local account the logon process is nice and fast. When logging into the user's new domain account (member of local admins group) it hangs on Applying Computer Settings for about 2 minutes. However, logging into a domain admin account the login process is fast as expected.
In an attempt to troubleshoot I've used WireShark to watch what's happening and it looks like the problem is coming from repeated requests and eventual time-outs with the following query:
NBNS Name query NB WPAD.ECCO.LAN, <00>
Where ecco.lan is our domain name. I've discovered that this is the automated proxy system trying to get its hands on a proxy config document, but we do not use a proxy at our site. After discovering this I turned OFF automatic proxy detection in IE, but no change.
I noticed a slight improvement after checking the order of the network interfaces; turned out that the LAN connection was last in line. After re-ordering those things picked up a little and here is where I sit with the 2min delay.
For some reason this search for WDAP.ECCO.LAN only occurs on the users account and not the admin account.
I'd appreciate any assistance in tracking this down!
