Cannot Change Computer Name or Network Name

[WarS]

Ive done a number of vLites of my original Vista wSP1 that came with my Gateway laptop. This isnt a restore disc but the actual OS disc.

I did a number of builds, and progressively started leaving in more and more options, until I had backtracked all the way out to completely unchanged.

Apparently using vLite in any way is causing me to be unable to change my computers name or network name.

If I try I get an error box that says "The following error occurred validating the name "anynameitry". A general network error has occurred."

If anybody has any idea what I could be facing or inadvertantly changed let me know. I didnt bother with a log as in my last builds I didnt change anything, just created Iso's of the disc.

Im not sure if I changed something that is needed as it looks like some of the previous inputs in stuff like services dont change from build to build.

Thanks !
