VPN doesn't work for only one PC

I have an office where everybody but one PC can access resources
on the corporate network but one PC. That PC can even access the internet but
nothing at corporate. I checked the VPN several times, it's fine, settings on that PC
are fine. I know that because intermittently the PC will be able to access resources
through the VPN  but after a few minutes it won't be able to anymore. I don't know what else to try, anyone ever have a similar problem?

thanks
ps: this is a site to site VPN from an xtm22 at the branch to the xtm510 at our corporate office.

I updated the network drivers, didn't update the BIOS. No new BIOS udpate available as of right now. I am not receiving any errors other than can't find domain controller to authenticate since all DCs are at corporate through the VPN which this PC doesn't seem to be able to access even though it's a site to site VPN and all other PCs are ok. I don't think that hotfix applies since this is XP pro SP3 and it's not a VPN client it's site to site VPN. I have re-routed everything on that PC through the insecure internet which is of course not a good solution.

Ok,

after combing more through various configurations like VPN configs on both ends, PC logs etc. we found something inside IE that was causing this problem. Under internet options>connections there was a MSN dialer added, once you delete that the work station gains once again access through the VPN to all the resources on the corporate network. It's crazy because why would something in IE be breaking the PC's VPN access to corporate and keep in mind it's a site to site VPN so there is no VPN client running on the machine itself. I am assuming some type of malware did it even though I couldn't find anything in any scans.

This is just my opinion,but it sounds like someone added a connection to gain access to the net outside of the vpn.Just a thought.

I don't know how they would have done it without being local admins, that's why I thought it was some sort of malware.
