Hi y'all and thanks for reading, I've tried to run de srvr.exe and empedit.exe examples in the Borland Examples directory and it worked fine. I tried to run the server on another computer, it worked fine (After running DCOMCnfg.exe and setting the clearances right). After that I created my own server program, which accessed a SQL server database via the BDE which works via ODBC. Everything works fine except when I try to open a ClientDataSet, which is linked properly to a TProvider. Then I get the error message: 'src->QueryInterface(GetIID(), (LPVOID*)(&intf))': Interface not supported ... What am I doing wrong? If I set the active property of the TRemoteServer to true, the server starts nicely. I also tried to use a TDCOMConnection instead of the TRemoteServer component. The same happens... Any idea's would by greatly appreciated... Erwin

I beleive that this was a BCB4 issue and a patch created this problem... check Borlands site for the fix for this... I think I read about it there.

Thanx very much !!! This is indeed the solution. I installed the first patch, but not the second. This solved it completly...
