I am a bit of a newbie when it comes to working with servers, trained in routers, firewalls etc primarily so please forgive any ignorance.
We have Windows Server 2003. All our computers run XP pro. Recently, some of our computers have become unable to access the shared file on the server. Most of our computers are fine, but two of them give the error message "the folder you entered does not appear to be valid. please choose another " when I enter //server/'shared' and when I go to browse other computers on our domain show up but the server does not. We are able to ping the server at these computers both by ip and name. We have had no recent changes other than converting our internet connection to static about two weeks before this began and some cleanup on all pc's (defrag etc). All computers appear free of any malware, virus, etc.
I have tried setting permissions individually by users, having it set to everyone, disabling all firewalls, etc and nothing seems to work. Any help would be appreciated
