Cannot Reconnect Remote Desktop Connection

[igotregistered]

Good afternoon all, newb here.

I have XP Pro on both my office machine and home machine.

After I've established VPN connectivity from home I connect RDC to my office pc to work remotely.

However, if I disconnect and try reconnecting later, I cannot.

The only way I can reconnect is to come into the office and reboot the machine.

Then the whole thing starts all over. It only allows me one connection each time. Then doesn't allow me to reconnect until the office pc has been restarted.

Is this the MSLicensing key on either machine? Does the store need to be deleted to renew the licensing?

Any help is greatly appreciated. Thanks to all in advance!
