One Windows XP (SP3) laptop cannot map network drives to any network system (server or workstation).
From Toolbar - Map Network Drives = A pop-up box appears stating "The mapped network drive could not be created because the follwing error has occurred: The request is not supported."
From Command Line Net Use = "System error 50 has occurred. The request is not supported."
From RUN type \\servername or \\IPAddress = "The request is not supported."
We can ping the servers by name and IP address. We can access the Internet. Email program works correctly.
System = Windows XP Pro SP3
Actions taken = 1. ran "repair" on NIC, 2. removed from domain and re-added, 3. removed from domain, renamed laptop, readded to domain. 4. Tested with user's profile and an admins profile. Same error regardless of actions taken.
