In the XP system, in the system attribute computer name, the network ID button is gray and unavailable. If you click on the change button below, the domain and work group you belong to are also gray and unavailable.

General solution: Type Msconfig during operation, check workstation service in the service tab, and just click! In addition, you can also select Management Tools---Services-----to turn on the workstation service in the control panel!
If you don't have workstation services, install the microsoft web client on your network!
But there was a problem when enabling the service: windows couldn't enable workstation on the local computer.
------------------------------------
In fact, the real solution is to copy the two files RDBS.SYS and MRXSMB.SYS from the normal computer's c:\windows\system32\drivers to the computer with the problem, and then turn on the above services and it will be okay.

The method verification is valid.
