Yes and I had to re-register again. I just came to my computer and saw message with username and stuff. Now this is my home computer but in firm I have about 50 PC's. OK if someone thinks that anyone who has this amount of pc's will go around and check clients now and then for error is crazy.

This is really a big problem for enviroment with more than 15-20 pc's.

I understand that it is a pain when these things fail. I have two computers that are about 1400 miles away. Other people that I know here have hundreds of computers running WCG. We all have the same fundamental problem. Each time a work unit is run, it needs to know which device it is running on so that it can report back correctly and the member can get credit.

Computers being what they are, fail in a myriad of ways. Sometimes I think it is just to irritate humans, but more likely not. The way that I keep up with my small herd is to just watch the device statistics on the website every morning. If all of them have reported in with a completed work unit in the past day or so, I ignore them. If not, I go visit them, or in the worst case send an email to their caretakers and we work on it remotely. It may not be the best solution, but it works for me.

Now, I still do not know for sure what the original problem was so, we will have to wait and hope we hear back from Chowbow.

OK, I went through ScanDisk first, which found no errors and then the floppy disk that came with my HDD, no errors.

Then Memtest86, OK. Prime95 ran for 21 or so hours, OK.

Couldn't tell you what went wrong, but both computers did have to re-reg in a window of several hours, and neither computer had any problems sending information in before. Could it be something on WCGs end?

I too have had to reregister a device after changing AV and firewall programs. I'm not sure which came first though (rereg or AV proggie).

What surprises me though is that when I reregged and checked in 'My Devices', I now had two machines with the same name (i.e. not unique), and that the Device Manager allowed me to reconfigure this second machine without complaining that the machine ID was already in use.

I know that at grid.org, Device Manager would have made the same initial display but would have not allowed me to continue until the name had been made unique (i.e. renaming the old device)

Is this something that makes WCG different to UD, or have I encountered a glitch in the system?

As a diagnostic, I should add that the new device seems to have been treated as a new device because the profile settings were ignored and defaulted to the standard settings.

As a failsafe, I have renamed the old device anyway, but am still curious as to what might have happened if I just let the old name remain running...

Thanks for your prompt reply!

That is interesting and a vast improvement on grid's agent (if I understand you correctly).

Is it safe to assume then, that if the whim took me, and I reinstalled the agent a 100 times, I could still retain the same name? If this is the case, then there certainly wouldn't be the same issue of ppl having only one machine, which because it has been reregistered x amount of times, now shows as having x amount of machines when in fact there is only that one machine.

It does appear strange though that I now an extra device showing on the 'My Devices' page whether I rename the old one or not. From what I have read in these forums, the same issues seem to be true both here and at grid.org.

I wouldn't like to upset things now that I have already renamed the 'old' device, but definite clarification would be handy should the same situation arise.
