unexpected crashes

Recently (for about 2 weeks now) we have been getting some unexpected program crashes with I.E. 6.0 and O.E.version 6. Here are my last three error messages in the last 24 hours:

AppName: iexplore.exe AppVer: 6.0.2600. ModName: lspcs.dll
ModVer: 1.0.0.11 Offset: 0000d002

AppName: msimn.exe AppVer: 6.0.2600.0 ModName:lspcs.dll
ModVer: 1.0.0.11 Offset: 0000d002

AppName: msimn.exe AppVer: 6.0.2600.0 ModName: lspcs.dll
ModVer: 1.0.0.11 Offset: 0000cfdf

Thanks for any suggestions here.

Windows XP SP1
512 ram

Here are my modifications, if this helps at all:

Since 6/25
Installed MSN Messenger 6.2
Removed MSN Messenger 6.1

7/2- Removed Net Nanny
Installed Cybersitter 9.0

7/3- Windows update V4

7/4- Registry First Aid

 

Thanks, I will try that.

 

You were right. I found out that Cybersitter is not compatible with XP and causes frequent crashes with I.E. No known fixes yet, according to company.
Thanks
