I have a workstation with Windows XP SP2 on it. About 2 weeks ago it started
to hang for no reason. I have run a full system scan with Symantec Endpoint,
I ran a full scan with Malware Bytes and both came up with nothing. I have
updated IE to IE 7. I ran a full diagnostics on all hardware and everything
checked out. I also ran a diagnostics on harddrive and all was ok. I have
looked and the Event log and the only error that keeps showing up is...The
LafService service failed to start due to the following error: The system
cannot find the file specified. I cannot find anything about LafService. Is
this a windows service or does it belong to another application?
I sure would appreciate any info on this.
Thanks,
Debra
