Domain, Workgroup, Network ID, PC name greyed out

Hello all,
First post not sure if its in the right spot.
On only one of my XP Pro SP2 machines, as of yesterday started to have an issue connecting to a mapped network drive. After some digging I noticed in the Computer Properties that everything was greyed out. Couldn't change the name, network id, domain, or workgroup. There is only one Administrator account on this machine and yes Im logged in as it. Ive checked the "workstation" and "net logon" services and they are running. Also "server" service is running. The tick mark is checked next to the "Client for MS Networks". No other issues are observed with this machine other than that so Im gunshy to call it a virus/malware. Ping works fine to and from it except for when trying to ping it by its conical name. You can access all files on each of the servers and can surf the net just fine.
If I reboot into Safe Mode, I can change the properties to rejoin the domain and reboot and everything works fine for an hour/day then back to square one.
Hoping someone else ran into this and knew what to do cause Ive tried a few with limited success.
Thanks all

Virus, used Malwarebytes and SP S&D both found stuff but still having the issue now more intermittently. Any advice outside of wipe and restore?
