Good morning gents!
Advantage Database server is from Sybase - they bought it from Extended Systems.
Andrew - thank you for straightening that one out - so my problems could therefore not have anything to do with the Advantage Database server - rats - I was hoping I was onto something.
Bruce - thank you for the follow up on the file - I checked the version of the file and it is exactly the one I copied to the system32 folder. I have just rebooted the server and reran ChkSys and it reports the same thing.
The servers we are running are 64bit so, all these modules are running 64bit...
Cheers, JK
