Hi Todd,
What function are you using to generate that error message (printing a QR report on IC, opening IC, etc)? Does IC pass an integrity check? Do you have full supervisory rights to the network? If it's printing a QR report, where are you printing it from (designer, printer, attached printer in IC)?
I don't believe that this message is being caused by Quik Reports, and that error message is not the one that was fixed by release 990428 running under Novell Client 32.
I would suggest copying the data to a local drive and try to do the same function. If you do not get the error message, then the issue is network related. If you do, then more likely it's a data issue. Also, can you create a brand new report on IC and print it successfully? If so, then perhaps the QR report file has problems.
