NDPSM Abends in NDPSM_CheckConn Process

Server abends in NDPSM module after server IP address has been changed.  Server will abend between 5 to 30 minutes after NDPSM has been loaded.


NDPSM debug logging shows the following:
Object: .DONT_PANIC.SERVERS.TREE
Error -603 (expected)
UniGetAttrVal() returned error -603 (expected)
Attempting to get "Network Address"


See Additional Information for an extract from the abend log.

After the server IP address had changed the 'LastKnownGoodSRSAddress' reference in, SYS:\SYSTEM\DPLSV386.REG was incorrect.

The line should be similar to the following:
"LastKnownGoodSRSAddress"="10.10.10.10:3018"

Also, check the SRS address in SLP is correct:
DISPLAY SLP SERVICES SRS.NOVELL


Once updated reboot the server to ensure the changes remain persistent.
