Trust Issue with Win7 on Server2003 SBS w/SP2 Domain

-

on win server 2003 small business server domain, have user who's using win7 pro. approximately month ago put laptop on domain, yesterday afternoon, couldn't login pc. error @ login screen was:

“the trust relationship between workstation , primary domain failed.” (or similar statement)

at company, ran same problem. in case , above case, removing laptop domain , re-joining solved problem. but, what's causing trust issue? laptops have these facts in common:

  • both laptops, manufactured different makers
  • they have used both wireless , network cables @ various points in time connect companys' domains
  • the users take laptops home , use them on home wireless networks
  • both on sbs 2003 server networks/domains
  • both organizations use symantec sep protection
  • they both have same win7 os version
  • i haven't had problem winxp pc's

after "solving" (or working around situation), i went user's add/remove programs , saw .net framework client 4 had been installed yesterday afternoon, through windowsupdate (since update has caused problems me on other pc's in other situations, and since laptop didn't need it, uninstalled , hid future updates).

in doing research, noticed mention of "serviceprincipalname" attribute. in looking @ properties of laptop in adsi, noted attribute multi-valued , had 4 values. 2 of values set host/[pcname] , other 2 started "restrictedkrbhost". other pc's on network winxp pc's. viewed properties of few of pc's. sampling had 2 values, neither of began "restricted".

a couple questions:

  1. in future, matter of going pc's adsi properties , removing "restricted..." values, rebooting pc-in-question , logging in?
  2. if can so, fix? (as opposed taking pc off domain)
  3. if can't above, there "easy" solution?
  4. what's causing problem? server upgrade solve problem?
  5. anything else should looking at?

thanks in advance . . .

1. not far can tell - expected...

2. can try resetting secure channel (http://social.technet.microsoft.com/forums/en-ie/winserverds/thread/23760978-0d91-4496-a2da-ef95ae9d5989) - if doesn't work, need resort removing/readding computer domain

3. ditto

4. failing secure channel - more @ http://blogs.technet.com/b/askds/archive/2009/02/15/test2.aspx

5. reach out sbs forum - since there might sbs specific caveats take account
