Cannot see my computer and others on LAN cannot see my computer in network

SysopChris

I have been networking since 1980 when I was building my own cables and using a COM port so this is just a little frustrating. I am an IBM AS.400 (iSeries) software developer/analyst and transferring data from different systems is my speciality but for the first time I cannot share a folder on my LAN for another laptop to perform an image backup. I spent last night looking at ETL and XML files created by the network troubleshooter.
I have tons of info. I could post but this is the most current.

Otherwise:

I'm hoping someone has seen this before and knows a quick fix.
If useful I have my complete XTU specs. posted on HWBOT.com.

Thank you for your reply. Due to audio latency issues that I could not solve I just recently performed a clean install. I could not listen to any audio without it sounding like a record skipping. I am just now getting Fing re-installed.

Regards,
Chris.
