DescriptionThe Microsoft Exchange Information Store encountered an unexpected exception 0xC0000005 at address 77F517DE while processing a request for user <user name>.
Event InformationThis information from some newsgroups may help you:
This problem may occur when there is a malformed e-mail message or other malformed item in the information store. Additionally, the processing of parameters in a HTML close tag may cause the Microsoft Exchange Information Store service to crash. A supported hotfix is now available from Microsoft, but it is only intended to correct the problem. Only apply it to systems that are experiencing this specific problem. The very first step which i would suggest is to install sp1 for exchange 2003. Install latest updates for the exchange 2003. Disable file level scanning for exchange directory on all drives. I mean all drives wherever the exchange components are installed. Try to verify what dr.watson.log says. Try to verify which service causes IS service to crash. This hotfix requires Microsoft Exchange Server 2003 Service Pack 1 (SP1). You must stop and then restart the Microsoft Exchange Information Store service when you install this hotfix.
