My colleague Abdul Aziz Marafi (owner of www. bateel-software.com), who has developed one of the most downloaded file and folder sync tools available free, had a problem once after he joined our local domain. The problem was simple, he could browse the network, however others cannot access his computer, cannot access shared folders etc…
The workaround was as simple as this, he removed the computer from domain, re-joined it. Bingo, it was easier than going through tons of technical manuals to find out WHY NOT!
