svchost instruction 0x0000000

I needed to remove NIS 2009 for Internet access problems.  Once the problems were fix, I reinstalled NIS.

 

Now I get svchost popup errors:   The instruction at "0x00000000" referenced memory at "0x00000000". The memory could not be "written".

 

I found elsewhere a suggestion:  To turn of DEP completely, go to the BOOT.INI file and edit the option /noexecute=optin to /execute

 

I am not to "keen" in changing BOOT.INI.

 

Is the a better fix?
