2008 Server Reboots when NT tries DCOM

[DMan65]

Hello Everyone,

I have some systems that are based on NT 4.0 that have to remain on NT 4.0 because they have hardware that only has drivers for NT. I am in the process of attempting to add a new application server that used a solid state "hard drive" which requires drivers for 64-bit Windows. This required Server 2008 64-bit.

Having setup the 64bit Server 2008 computer, I am attempting to setup ActiveX exe components that we use in our systems.

If I connect to Server 2008 from a Windows XP or Windows 2000 client, I can
attach to a network share and create and use DCOM components without an issue.

If I connect to Server 2008 from a Windows NT (SP6a) client, I can attach to
a network share without an issue. However; if I attempt to create a DCOM
object on the Server 2008 machine from Windows NT 4.0, the Server 2008
experiences an RPC error and then reboots.

If it matters, I have tried this with the firewall turned totally off and I
have tried it with the firewall on and the only exceptions being
Core Networking
File and Print Sharing
Remote Desktop
srvrQueryArray (The object I am testing to create)

The results are the same either way. I have reformatted and reinstalled
Server 2008 since making this discovery and the results are the same with
every installation. I have tested all of the involved machines for viruses and none are present.

The errors reported by the server are:

There is a thread here that should help you. Do a search for dcom the site and you'll find it.

Thanks for the reply. I hate to be dense, but when I search for dcom I only see 4 posts including this one and none of them seem to address the issue I am having. Do you have a link to the thread by any chance?

Thanks,

Darrell

Thanks for the link. I did see that, but it appears to be a different issue.

I can create the object on WS 2008 without any difficulty if I call from Windows 2000 or Windows XP. But trying to create a DCOM object from Windows NT results in the RPC service crashing on 2008 and the computer rebooting.

It looks like I am going to end up "downgrading" to 2003.
