UREGNT - Join to domain remotely and create a profile

Our CEOs remotely located PC had some problems and we had to rejoin it to the domain, we use Sonicwall VPN client which doesn't allow to logon to VPN before user logs on to his profile. Now for some reason, we are not able to logon the the his domain profile, only to local profile, which works somewhat but it's not the perfect solution. After his estabilshed VPN connection he can access shared drives and connect with Outlook to Exchange but he getting misc logon prompts more often then he used to, which is annoying for him and we just want him to be logged on to his domain account. We have remote access to his PC via Logmein. I know that you can create a domain user profile only when connected to a domain, but maybe there is a trick, to do that some other way? Even though it seems like the old domain profile account is still there under Documents and Settings, but when I try to logon as domainname/username it says it can't contact the domain controller, which is obvious because the VPN connection cannot be establish before he can logon and start the VPN client

Any ideas if there is some way do that remotely, or I shouldn't waste my time and just have him bring the PC back to the office to create his domain profile account?

Thanks
