Basically, SBT is a network-based accounting system and do not requires you to setup a workgroup or a domain. Any of this network configuration is enough to make sbt system working. just make it sure that the your sbt server(location of sbt system in your network) is visible.
The file that missing (syccacc.dbf) is one of the dbf loaded in the system every time you wanted to make access in sbt system. I believe this file is not remove on your sbt active directory (the pro50 of sbt engine). Assuming you have sbt system file in "q:\pro50" and datafile in "t:\pro50"...
Please make sure to synchronize the ff:
1. Check the properties of the icon of sbt system(The one you click to open sbt, maybe on desktop or program file of your operating system).
TARGET : Q:\PRO50\SBTW.EXE
START IN : Q:\PRO50
Please note the ff:
1. folder or directory of q:\pro50 is the location folder where your system files such as the sbtw.exe, SYCCACC.DBF, syccomp.dbf, sycdata.dbf and more are EXIST. If these files are in other folder, please have it named to the correct directory. My sample is at "Q:\PRO50"
2. My sample datafile of sbt at "T:\PRO50" is the directory where you will find the \ARDATA, \APDATA, SODATA.... But pls dont confuse of this "T:\pro50". I just emphasizing the details of my sample datafile but nothing to do with your problem.
