I know there are other threads and discussions on this. I'm wondering if anyone has discovered what is causing this. I only have 2 windows 7 x86 systems on my network right now. My system and another guy in the office. They retrieve updates from an eras system along with all the other systems which are winxp and server 2003 machines. My win7 system has been on the network for quite a while, since the first of the year or so and there never was a problem until about 2 weeks ago when the compiler errors began during updates. The other guy started with the compiler errors very shortly after I put the machine on the network which has been a few months now. I did run the eset removal tool on his system and re-installed, but the problem still occurs. This occurs on both systems about once a week. Clearing the cache and a reboot fixes it, but I can't have this going on all the time. I need to get this fixed cause I don't want to start putting a bunch of Win7 machines on the network and having this issue with all of them. These are new dell optiplex machines in an active directory network. Anyone get an answer from Eset on what causes this?
