Netware6.5

Our customer uses netware6.5 with sp2.

The nss's data pool corrupt, so people try to rebuild it.

However, it doesn't work properly.

nssstart.cfg
server -ns
startup
loadstorage 1

:nss /poolrebuild=data /purge
=> Loading Module NSS.NLM [NOT MULTIPLE]
We are in stuck here.

What should i do now?
Could you give me a cool solution?
