Restored the SYS:PUBLIC\WIN95 and SYS:PUBLIC\NLS\ENGLISH and the DS error -128 did not occur again. The version of Z.E.N.works that was installed on that server could be reinstalled to get the files current again. Any patches that had been applied would have to be reapplied if the reinstall was done.
Another environment reported this problem when installing the zen 1.1 from CD. If you install it from the Starter pack off the WEB then it appears to have the updated NRD files in it. So reinstalling ZEN from the starter pack and verifying it updates the NRD files should correct the problem.
Customer Reported: After installing the ZEN 1.1 Starter Pack, Verify that the NRDDLL95.DLL (1 May 1996, 11:19:24 am, 159744 bytes) was replaced with the version dated 2 July 1996, 05:48:58 am, 157696 bytes (obtained from another server). After doing this, the SYS:_NETWARE NDS files were not held open.
Key words: NRD, NRD:, NAL, ZEN, Z.E.N.works, DS, -128, Locked, Mixed, NRDDLL16.DLL, NRDDLL95.DLL, Streams.
