[Zope] Zope on Win NT

hi all zopists, i have seen how zope works on linux when one of my friend happened to install.. and it didn't take me any time to get a comfy feeling with it. now i am trying on win nt platform.. and face some problems.. the initial installation or the start.bat doesn't get executed properly stating errors like "could not lock the database file. there must be another process that has opened the file." when there's no process which is using it. looking forward for some urgent assistance on the same. thanks and regards, madhavi.
