Hi, first sorry for my bad English. Recently my company did a network upgrading (changing several units of old unmanaged 100mbps switch to a new managed 1gbps one, and do a correct new backbone cabling to avoid looping coz old cabling is a total mess). Everything went fine for a while. Then suddenly a week ago we have some weird connection problem with all PC in LAN. All PC can ping any PC fine, but cant sharing with each other. If i restart the PC, then it can sharing for a while before the problem come again. I try to do \ip_num but it just give me error of not accessible etc, and then the PC will become crazy soon afterward (taskbar missing, system32 error, freeze etc) and had to restart.Just one evening few days ago the problem seems to be gone for a while, before it came back next day morning.All internet connection is fine.Is it something to do with switch looping? There about 150 PC using XP Pro SP2 and several server (Linux and 2003 server). No domain, just normal workgroup. Please help.

Thanks. We'll let you know when a new response is added.

According to Microsoft, XP Pro Workgroups become impractical in environments with more than 10 computers. You need to upgrade to a domain.

============

Apply Microsoft updates. It is possible that there is malicious software running on your network creating these problems. As the previous poster suggests, peer-to-peer XP workgroups for this large of an environment is not recommended. It would be best to implement an Active Directory environment for a network this size. You can also use a sniffer like Microsoft’s Network Monitor or Wireshark to see what the traffic is actually doing on the LAN. Take a look at the client machine’s event logs to see if they can shed any light on this issue. This is likely not a network (switch) problem but a desktop or server configuration issue. Scan the computers using a good, up-to-date antivirus/spyware application and resolve any issues found.

    I agree. This sounds more like a virus/spyware problem. Do you have some antivirus software installed on your network ?

    XP PRO limits the network share connections to 10 at a time, meaning you can only have 10 users connected to any shared resource at any given time. XP Home only allows 5 connections to a single shared resource at any given time , according to MS you have way to many connections trying to connect to any single shared resource on this workgroup. Try this test, have 9 or less users sign on to the workgroup, and have them access the same single shared resource on the workgroup, i.e, a shared folder or a shared printer, to see if everything works. If it works for these 9 then I would bet it is not your switch or the cabling.
