AX 2009 (Ax32Serv.exe) service crashing

Hi All

I am new to this dynamics stuff but have a problem I just cant figure out. In the event viewer I get 2 messages and after the second message the AOS service crashes (see the messages below)

First message

Object Server 01: Unexpected situation

More Information: Delayed change company RPC failed.

Second message when AOS crashes

Faulting application Ax32Serv.exe, version 5.0.1000.52, time stamp 0x490c68d8, faulting module kernel32.dll, version 6.0.6001.18215, time stamp 0x4995354a, exception code 0xc0000005, fault offset 0x000000000002619d, process id 0x%9, application start time 0x%10.

does anyone have any idea why this may be happening or any ideas on how i figure it out
