An IT tech was called in to remove malware, run antivirus, and generally attempt to speed up the PCs that run the register software. The system consists of one server and three clients. After he completed his work we proceeded to start the POS software and continue work. One of the client machines refuses to allow SO to start and stops before the login screen appears with an error stating that the pdatall.dll file cannot be found.
Through SO Administrator I have successfully connected to and successfully tested the connection to the SQL Server backend. After running a few more checks it appears this error is confined to this machine as all of the other SO installations function correctly. I have attempted to repair the installation via Add/Remove programs and by using the installation disk but the issue remains. I have also tried using a replacement .dll file as well as registering the .dll again but to no avail. I am the registered partner and have consulted with MS support but they have been unable to offer a solution.
Aside from a complete reinstall, is this an issue that someone has encountered before and can it be resolved?
