RPC service unavailable on NT

[Garry Baird]

Hi All,

Sorry for cross-posting, not sure if this a WLS install problem, WLS
security problem or something else!

I've recently had to reinstall NT (4.0, SP4 - we've upgraded our hardware
configuration, including a CPU upgrade to an Athlon 1GHz processor, and were
advised to reinstall NT rather than restore it from a disk image) and WLS
(5.1, SP5) on our development machine. The install appears to be identical
to the previous install of NT and WLS, in terms of settings, services, JVM,
JDK, etc. but I hit the following exception when starting WLS and using
NTRealm (it worked fine on the previous install). It works fine if I don't
use NTRealm but as we don't have userid's/passwords in the
weblogic.properties file (only groups) it's not much use!

I've checked the following services which all appear to be installed and
running correctly:

RPC Configuration added as a service via Network Properties
Name Service Provider is Windows NT Locator
Security Service Provider is Windows NT Security Service

Via Control Panel -> Services
RPC Locator service is started (automatically)
RPC Service service is started (automatically)

The only 'visible' difference is that the previous install of WLS was from a
download from the BEA site and this install was from a WLS CD as provided by
BEA. I would have thought they would be identical though.

Anyone else hit this problem or know what else I can check?

Thanks in advance,
Garry Baird.
