I have a lot of PCs that are running a combo of XP SP2 and SP3 that will randomly stop working and the windows zero configuration service will be stopped and or disabled. They are associated with Cisco access points 1232 access points running LWAPP. Wireless signal strength is not an issue. No coverage problems. I have a small wireless lab setup with 6 wireless laptops all running XP using 802.11G at 54 megs and some will just randomly drop connection and when I go and look the wireless zero configuration is disabled. I use only the built in WIndows wireless to manage my connections. When they stop working they stop working all at the same time, but not all. Some will continue to work just fine. I dont know what else to look at. Has anyone else had this same issue that has a fix? I am currently upgrading the WLC to a new code to see it that has any resolution. The problem is that it is so random I cannot duplicate it.
