VPN-and WIN2k Server spk-2

Did anyone run into a problem once the updated to service pack on there server? For some reason, my application (Syspro's Impact Encore) wont run on win98 remote users via VPN yet works fine via RAS. And even though I can run the program on versions later than win98 (1st edition) I've lost the ability to priint? since I've updated to the newest service pack? Has anyone else out there run into a similar situation? How were you able to resolve it? Any and all comments would be great. Oh since Encore is the only application Im running over VPN (oh and any nice tools that can be run in this manner would be nice too) I'm not able to actually pinpoint the problem. Encore does work fine via dial-up, and prior to spk-2. Any Encore Users here?
