From my research everything points to Peachtree as being very unstable on a network. Any type of network anomoly can cause a peachtree company to go bad, especially when the company is being written to or read from. This is due to the structure of the peachtree datafile. Peachtree is a much better when used on a stand alone machine with and UPS attached for any power outages, giving the user time to close out the company safely. The makers of Peachtree do make a better product for network accounting, but is used mainly in accounting companies and not for the one company user. I don't know if this helps, but thought I would let you know of what you are dealing with. It is very expensive to fix a corrupted peachtree company, and requires the use of Pervasives Betrieve Data engine running as well as some specialized software, I have had to fix a number of peachtree companies and it is no easy task. In summation Peachtree, as stated before is not made for the network, and as much as Best Software would like to not admitt it those are the facts.
