Why?

Well here is an interesting story for the day. The background we have a "sever" at work that stores all our POS and shop management software. And even though I'm not really an IT guy I know how the system works I know how to fix things when they are not working on our computer system. We have three computers and they all feed off of the "server" Including my workstation at the write up area. So this morning I am working away we had a few cars here so I had some estimates to work up. Well to do this I need to get into "The Labor Guide"> on the "Server" it is simple really point > click > it opens up. Well rather then it opening this morning I get an error saying "The Shop Key Parts and Labor Guide is not installed on this machine. Please call ###-###-####." (Thinking to myself ah......... I just used it 5 min. ago WTF?) SO I start doing some checking........ After many checks I found that the "data path" had changed ie. where the computer looks for the information. The server drive is "Z" on our system it was looking for the info on my local machine's Drive "C" Now I didn't change anything how did it change itself and within a few min. time? Is it a virus? I don't think so Norton has not picked anything up.

Just some stupid things that make you go hmm.. LOL
