MS Outlook not able to start up - Host Process (Rundll) Crashes

Posted on 2008-06-18

I was hoping someone could help me with a problem I've been having since yesterday afternoon. Yesterday morning I checked my email with MS Outlook without any problems. I shut down my laptop (Vista did not apply any updates when shutting down), hit the road, powered it back on, and tried to check my email again. I got the message:

"Microsoft Office Outlook has stopped working.
Windows is collecting more information about the problem. This might take several minutes."

I've been trying to get it working since yesterday. I haven't found anything useful on the net to help resolve this issue. I've gone as far as uninstalling the whole MS Office suite and reinstalling.

I have also noticed that if I go into Control Panel -> Mail -> Data Files (or Email Accounts) that it will report an error:

"Windows host process (Rundll32) has stopped working"

I went into the Event Viewer -> Application to see if I can find out more details and this is what it gives:

"Faulting application rundll32.exe, version 6.0.6000.16386, time stamp 0x4549b0e1, faulting module RPCRT4.dll, version 6.0.6001.18000, time stamp 0x4791a751, exception code 0xc0000005, fault offset 0x000a1a96, process id 0x%9, application start time 0x%10."

Every other application on the system is working just fine...

Can anyone help me figure out how to resolve this issue?

Thanks in advance!

Sig[5].Name=Fault Module Timestamp
Sig[6].Name=Exception Code
Sig[7].Name=Exception Offset
DynamicSig[1].Name=OS Version
DynamicSig[2].Name=Locale ID
UI[3]=Windows host process (Rundll32) has stopped working
UI[4]=Windows can check online for a solution to the problem.
UI[5]=Check online for a solution and close the program
UI[6]=Check online for a solution later and close the program
UI[7]=Close the program
AppName=Windows host process (Rundll32)

After going through and debugging in-depth, here's what I did.

I had another Vista computer that I tried bringing over the c:\windows\system32\RPCRT4.DLL file from (1.2 mb with the new file versus ~720k with the old) (I had to boot up via F8 and go into a command prompt). I gave that a shot and rebooted. Vista failed to start, rebooted, and then gave the black screen saying the previous startup attempt failed. It prompted me to try and repair the computer. I did. I believe having it go through these tests and attempt to fix it resolved the problem.

I imagine if I would have just tried booting up via F8 and "Repair Computer" and then scan & repair computer it would have resolved it. Maybe it needed to relink some DLL's or whatnot.

Anyways, this resolved the problem and my Outlook is fixed.
