WRITEVALUE("HKEY_LOCAL_MACHINE\Software\Microsoft\SMS\Client\Sites","Site List","200|", "REG_MULTI_SZ")

but for some reason it didn't work (inserted extra return), however when I retyped the code it worked... go figure

ScottH,

REG_SZ is for a single string, the registry entry that I was trying to change was a Multi-string, so I had not choice.

Thanks
Michele
