SP2 strikes....

By caestelle ·
I know this is a long shot, but here goes?

We have a client who is getting an ?Error 70: permission denied? error when launching our software and I am running out of ideas. What is going on behind the scenes when this error occurs is that it is trying to create an object(list box) that will eventually be populated with a list of databases that can be logged into. Both the server and the client are Windows XP professional machines and our software worked just fine on them until they updated to Service Pack 2. We have done extensive testing with our software on Windows XP sp2 and it works fine. I have checked all of the COM+ settings and MSDTC settings on both the client and server side and everything appears to be configured correctly. I have also checked user permissions on both the client and server side and again everything appears to be setup correctly. I have attempted to replicate their environment in our test lab and I am not running into any problems. We have several clients running our software in essentially the same environment and they are not experiencing any problems.

To give you a little background on our software, it is a client/server based software that uses COM+ applications and MSDTC. The server side consists of an SQL database and several COM+ applications and the client side consists mostly of application proxies. It was written in VB6.

Any ideas?? THANKS!!!

I can't swear to it, but I do know that Windows 2003 SP 1 changes the security model for RPC and COM+ authentication. I wouldn't put it past Microsoft to have placed that authentication model into the XP update also, to ensure compatability with Windows 2003.

Just one really stupid question which I am sure you have checked, does it work if you turn off the Windows firewall and do they have ports 135-138 blocked so that RPC sessions can't be formed betwene systems? That might well be the source of the issue.

Have you tried turning off the firewall SP2 automatically puts on your boxes?
