I know some of those .reg files are specifically for sme as a domain controller but I was wondering if any were applicable in a workgroup environment.
AFAIK they are only required to be used on workstations that wish to join a sme server Domain.
We are seeing some strange behaviour with a commercial application running on windows 7 clients to a workgroup share on sme.
If you want useful answers from here, then you need to tell us what that commercial application is & describe that strange behaviour.
It is quite possible that some other user has already experienced your issue.
I know of "commercial accounting/database applications" that are not supported on Linux, purportedly due to "timing" issues (maybe "race" conditions) & the software authors advise that it is only supported to work on Windows based servers.
Try running the software across the network from an install on a Windows workstation share, & see whether you still have problems or not.
You may need to setup another Windows server or run Windows in a virtual environment on your sme server. If you only have a few (less than 10) users accessing it, then you can use Windows workstation software rather than a full blown version of Windows server software.
