We have NOD32 running on a number of sites now but this is the first one with this issue, I am open to any suggestions. ERAS is installed on the main file server (SBS2003) and configured to allow updates via HTTP or file share to the clients. However none of the clients will see the updates via either HTTP or the server share, giving a missing file error. Thinking it maybe an error with the server I set up one of the clients (one of the few with internet access) to act as a mirror via file share but again i got exactly the same error with another client pointed to the share. If I open the share in windows explorer all looks fine. If I copy the files to the local machine and update from there it works OK. The interesting thing is that all of the clients can happily report in to ERAS to say that they arent updating. The setup seems to be identical to those I have set up at other sites but I've not had this problem.
