Since this morning my w3wp process keeps crashing whenever I try to open an application on the server (IIS7.5).

This is the error as it appears in the event log:

Faulting application name: w3wp.exe, version: 7.5.7601.17514, time stamp: 0x4ce7a5f8
Faulting module name: MSVCR100.dll, version: 10.0.40219.325, time stamp: 0x4df2be1e
Exception code: 0xc0000417
Fault offset: 0x0008af3e
Faulting process id: 0x14d0
Faulting application start time: 0x01cc5d78b3257d74
Faulting application path: C:\Windows\SysWOW64\inetsrv\w3wp.exe
Faulting module path: C:\Windows\system32\MSVCR100.dll
Report Id: f0dcc5a8-c96b-11e0-ae82-5c260a4cea30

Anyone have any idea? This is quite critical for me to get it up and running again quickly!

If the system has worked prior to this situation, then the possible steps/approaches to consider:

  1. "chkdsk c: /r" to assess and address any possible errors (it may fix the file fault, if on exists)
  2. replace the MSVCR100.dll file (from backup or original installation)
