Have you had a chance to verify that the time of the workstation is in sync with that of the domain it's trying to contact? 
 
A good article to reference would be http://articles.techrepublic.com.com/5100-6345-1060499.html. 
 
Just a thought...

Subject: Re: [MSUNAG] Wierd issue with IMC domain 
 
Scott,  
 
I'm hunting down a similar issue in a another ad.msu.edu domain.  
 
On problematic workstations, Start>Run>\\domain.ad.msu.edu fails and users  
experience painful logon times. Ping\nslookup for domain.ad.msu.edu does  
work. DNS\WINS is consistent with working workstations.  
 
You are using imc.ad.msu.edu, correct? Give me a call, I'm glad to help.
