What is the best way to trouble a network connection? I have my lan all on gigabit and I'm having a problem with one pc connecting into a database on one of my other pcs. It is just crawling and very very slow accessing the data.

Is there anyway that I can troubleshoot the connection to verify whether or not there is an issue with the connections somewhere?

Thanks!

Of Course there is a way to troubleshoot your network connection. It all depends on your network. Here are a few questions to help determine the direction you need to go in. How many machines on your network? How far apart are they? Do you have managed switches? Do you have a cable tester?

i would start with changing the network cable from the slow machine to the switch. Is check you network adapter. Does it have the latest drivers? Is it slow doing anything else on your network? Is it good? Try changing it out. Scan the machine for viruses and adware. Do you have any software firewalls running on the suspect machine? Get a good cable tester that can tell you if a line is bad and how far away it is bad. Any other machine having problems accessing data? if not are the settings the same as on the slow pc?

Start with that. Try eliminating your hardware then move to software or vice versa. i always try to eliminate the easiest thing first and move on to the more difficult. good luck

Always assume the cable is bad.

Second check speed/duplex on the NIC and switch port. Both sides should be auto or forced to the same speed/duplex. Lots of people will for their NIC to 100/full thinking they get better performance - what really happens is you get pitiful performance because the switch is set to autonegotiate and will default to 100/half.

9/10 problems are the cable.
9/10 performance problems are speed/duplex mismatches.
