that the only Google entries for this vxdisrva are your own searches for a solution to this, and there is nothing else available in searches.
Congratulations, it's not often we are the 'only' contributors to a word or phrase,
It seems you have already searched through MSCONFIG, the System Configuration Editor and you have stated it could be something you have disabled there. I'm surprised there is nothing definite though because if this error occurs on each boot up, I would have expected that the MSCONFIG utility Startup tab would have shown a PATH for some Legacy software. I have found that the column for Path in MSCONFIG has to be stretched to the right by dragging the column header to see full path entries.
I wouldn't suggest tampering with the registry as that could cause other problems, although you could have a quick look at the Run, RunOnce etc entries as explained here;
They may offer some clues.
Other than that, you may have found a further clue in the other Event Viewer entries, eg "DCOM 10005 errors (service database locked)". it may be worth exploring that further.
Let's hope others here have better ideas.
Does anyone know what the vxdisrva service does?
I get an error message in the system event log every time I boot telling me that the service cannot be started (file not found).
I have searched the web but can find no reference to a service of that name.
I am running xp pro + service pack 3.
I could simply remove the registry entry that attempts to start the service, but I would like to know what it is first.
It might even be a virus/trojan.
