I am having a problem with about 10 workstations out of 2000. I recently setup WSUS and pushed out the settings with group policy. This could be completly unrelated but now those 10 computers are unable to access our servers. They can connect to the internet and any website but nothing through netbios. The computers are all having problems starting the "workstation" service which means all the dependancies fail. when i try to start the service manually i get an error "The Workstation service terminated with service-specific error 2250". Another strange thing is even though the user account i am logging in with has full control of "c:\winnt\system32\drivers" it gives me an access denied when i try to open the folder. once i take ownership of the folder it lets me in but still can not read the files properly and screws up the network card. so it will not pull an IP. I dont know what this could be as i couldnt find anything on it when i was googleing. Thanks for any help.
