I am using windows 7, I cannot connect to a shared network drive on another machine.

1. I can ping the machine.
2. I can remote desktop connect to the machine.
3. The machine is on the same subnet
4. My friend with the exact same laptop as me (and on the same network, same workgroup) can connect to the shared folder.
5. The machine I am trying to connect to and my friends machine can both see shared folders on my machine.
6. I also cannot see shared folders on the friends laptop.
7. When I select diagnose, windows tells me nothing useful.
8. When I select see details on the error pop up, I see: Error code: 0x80004005 (google doesn't help much)
9. I can nbtstat -a the machine who has the shared folder.
10. When I try with my firewall turned off the same happens.
11. I have ensured my windows 7 has all updates.
12. I run security essentials to ensure my laptop is clean.
13. I run ccleaner to clean up my registry. Same error.
14. I have tried with my laptop on both wireless and ethernet.

As you can imagine, I am banging my head against the wall on this one.
