Last week we started having a problem with SVChost stopping on all windows 7 machines in the domain. The machines that are affected are not all the same either. The users notice it by getting red X-es on all mapped network drives, and they are unable to open some files on thos network drives. I can not go around uninstalling and reinstalling all the nics on all the equipment, that would be problematic :-) Any suggestions? <?xml version="1.0" encoding="UTF-16"?> <WERReportMetadata> <OSVersionInformation> <WindowsNTVersion>6.1</WindowsNTVersion> <Build>7601 Service Pack 1</Build> <Product>(0x30): Windows 7 Professional</Product> <Edition>Professional</Edition> <BuildString>7601.17640.amd64fre.win7sp1_gdr.110622-1506</BuildString> <Revision>1130</Revision> <Flavor>Multiprocessor Free</Flavor> <Architecture>X64</Architecture> <LCID>1033</LCID> </OSVersionInformation> <ProblemSignatures> <EventType>BEX64</EventType> <Parameter0>svchost.exe_NlaSvc</Parameter0> <Parameter1>6.1.7600.16385</Parameter1> <Parameter2>4a5bc3c1</Parameter2> <Parameter3>WINSTA.dll_unloaded</Parameter3> <Parameter4>0.0.0.0</Parameter4> <Parameter5>4ce7ca3c</Parameter5> <Parameter6>000007fefc902560</Parameter6> <Parameter7>c0000005</Parameter7> <Parameter8>0000000000000008</Parameter8> </ProblemSignatures> <DynamicSignatures> <Parameter1>6.1.7601.2.1.0.256.48</Parameter1> <Parameter2>1044</Parameter2> <Parameter22>f96f</Parameter22> <Parameter23>f96fd3ace348f667efcf41da49bf4c0b</Parameter23> <Parameter24>089b</Parameter24> <Parameter25>089bd190288e9616874fc67e4898035c</Parameter25> </DynamicSignatures> <SystemInformation> <MID>D663B5E5-2AF1-4DA6-BF1A-83CB251AAAA0</MID> <SystemManufacturer>Hewlett-Packard</SystemManufacturer> <SystemProductName>HP EliteBook 8540w</SystemProductName> <BIOSVersion>68CVD Ver.

It seems that the LanManWorkstation service stops and causes this problem. Hmmmm, digging along
