Does anyone know the registry setting for turning off My Network Places
ability to scan the network for shared folders and printers?
Windows Explorer | Tools | Folder Options | View tab;
Un-Check 'Automatically search for network folders and printers'.
If you need to do it via the registry, google for 'XP netcrawler registry'.
There is a value called NoNetCrawling, but I can't remember exactly where.
HKCU or HKLM\windows\current version\explorer\advanced, I think.
