On your PC:
Start-> Programs-> iSeries Access for Windows-> User’s Guide
Then expand Messages-> iSeries Access for Windows messages.
Scroll down to the CWBSY1008 entry, and open it. See if the Cause and/or Recovery give you directions to look. If those don’t help, there may be nothing we can do.
All of iSeries Access help assumes valid licensing, valid system configuration, connection to the correct system, etc.
