My quickbooks2003pro uk version is behaving weirdly, its a five user installed on five machines, the company file is on one of the machines in the network (LAN) all machines are running on winxp pro. When i open my company file and switch to multi user mode and then try accessing it from any of the other machines via the network i get the message: (the file is already open by another user make sure it is swithched to muti-user mode and try again) yet the file is already in multi-user mode, when i try accessing any other file on the client machines fom the server (company file host) it gives me a dialog box where to enter user name and password where as none of this is enabled, i give any password and it tells me it is incorrect. Redoing the network and re-installing of the quickbooks hasn’t helped, what could be the problem?
