For 7 years, my Windows 2003 server has crashed multiple time requiring a reboot and hours of IT time. Almost always, it is an IP address error. Over 5 IT companies have had a crack at it, and none have resolved my issues. IT companies in our area open and close frequently, and none have been very helpful. Last week, when the system crashed and the IP address error surfaced once again, it took 5 hours to fix, as usual. The IT tech though, asked me afterwards if I knew why the cable modem input first went to the wireless router which then sent the information to the server which then communicated with all of the 15 hardwired computers. This would certainly explain why the wireless laptops could access the internet at times when the wired computers could not during the recurrent IP conflicts. He surmised that the wireless router was assigning IP addresses to the server which was creating the problem.
If the above makes any sense, would anyone know why my network was set up this way? Are there any reliable online companies that can remote to me and work to address my continuing IP conflicts?
