basic troubleshooting

[rds747]

Ok Cisco experts I need your help...

One section of users had problems logging onto the domain. The ethernet card was working fine (had the green light on) on each PC. My supervisor pretty much turned the switch on/off (recycled the power) and everything worked fine. If that hadn't worked what are some other basic troubleshooting steps that could be tried.

Thanks.

Hard to say without knowing your topology... but I would have looked at the logs, interfaces to root switches to ensure they were forwarding traffic. etc....

Its possible you may not have portfast turned on which can cause problems logging on the domain or pulling an ip address if using dhcp.

I agree with viper... Generally, if you are plugging hosts into a switchport you should have portfast enabled so that the port doesn't have to go through all of the lengthy port negotiations. This feature, however, should not be used for ports that go to other devices like hubs, switches, routers, etc; because Spanning Tree needs to compute the root switch.
