In a small office ( far far away , just kidding) there are 4 xp workgroup computers and a new windows 7 pro build 7600 laptop. The laptop is on the correct workgroup and the folder needed for sharing is in Users\public\scans.
All the advanced settings for file sharing are set correctly and it is a "work" network. The reason for sharing is a richo multifunctional device than has it's own ip address and sends scanned documents to each machines scans folder.
For some reason file and printer sharing never managed to get set on the lan network card ( ipv6 disabled). When i turned this on i could see for the first time the windows 7 machines in browse workgroup from one of the xp machines ( and then hopefully the printer could see it ) but on double clicking the windows 7 machines in browse to see what was shared on the 7 machine , i got a permissions error to access the 7 machine's share. That i coulld work with BUT BUT since that moment the windows 7 machine hasn't appeared in the browse workgroup. IT has just disappeared !!!!.
This hopefully is a simple process ! sharing a public folder between windows machines but hell no.
Ideas on the dis appearing workgroup machine please. !
