Domain – Can not join comp to the domain… greyed out

domainwindows-xp

I have an old WinXP Pro SP3 computer I need to join to the domain, simple right? not really. When I go to control panel -> system -> computer name and click on CHANGE ("rename this computer") everything is greyed out. I can not set it from workgroup to a domain.

I am logged on locally as an admin. (Builtin account and one I created)
I have checked local policy (gpedit.msc) on the comp, but it feels like a needle in the haystack. I could probably reload an image faster than trying to fix this…but I am curious so I post here to see if anyone knows of it/fix.

I tried reseting the policy to defaults, but no luck:

secedit /configure /cfg %windir%\repair\secsetup.inf /db secsetup.sdb /verbose

EDIT2: Computer Browser & Workstation Services are not running

  • The Workstation service terminated with service-specific error 2250 (0x8CA).

  • The Computer Browser service depends on the Workstation service which failed to start because of the following error:

  • The service has returned a service-specific error code.

  • Could not load RDR device driver.

EDIT3: "mrxsmb.sys" in system32/drivers is a trojan, which is needed for WorkStation

Client for Microsoft Networks needs to be installed and enabled on the network adapter that is on the Windows network.

Then determine if your workstation service is started. The workstation service is required to join a domain:
