OLE exception while regestring exe (DCOM related)

[chethanjasi]

Hi

I am trying to call a server exe (ref DCOM component )on server machine from Client using local administrator account having full access permission.

the server exe which when executed register creating an entry in DCOM config.

This works absuletely fine in 2000 and XP(xp: ofcourse with slight access change in DCOM setting)

But In VISTA it throws me an OLE EXCEPTION.

I tried running the server exe directly in VISTA but the problem remains the same.
[it fails to register and create an entry in dcom config but after the exception server finally runs ]

i am struck up in this issue from past few weeks

Below solution was helpful for XP
To check DCOM configuration on Windows Vista and Windows XP
1. Open a command window.
2. Type the following command: dcomcnfg(The Component Services window will appear.)
3. Right-click My Computer, click Properties.
4. Click the Default Properties tab.
5. Make sure that EnableDistributed COM on this computer is selected.
6. Make sure that Default Impersonation Level is set to Identify.
7. Click OK, and then close the Component Services window.

Pls do reply
Thanks in advance

Hi Johngalt,

One more update is I tried running the server exe directly in VISTA with Run as administrator property by right clicking on the exe and it works!!!!!!

It has created the component in DCOM as well.

But if i access the server remotely from the vista Client now i get a special error saying Error OLE Exception : Accessing the OLE register and fails to establish the connection with server.

Any idea wat can be the problem ??
