Thanks everyone.
Between the holiday and my daughter's upcoming wedding, I've been quite overwhelmed.
Agree that implementing the tests described above makes sense but can't find the time. My $50/hour IT guy is against on-site server due to the cost of upkeep and security management. He suggested a direct line connection to AC server to make sure the antivirus wasn't causing an issue and wanted a AC conference call but the email to support was never answered/lost.
On 1/3 AC will move the data base to their in-house server, so we'll see how that goes. Right now, I need to look up a patient and send out a prescription. Can't log into AC because after connection established I get a "runtime error" and am disconnected. Tried another computer with same problem/error message. left a message with AC support...we'll see how that goes.
