I've had absolutely no luck figuring this one out, and it's finally annoyed me enough to post it 
In short:
For some reason, my HTPC has issues accessing files on my server (Lengthy loading times for things that should be instant, hangs in the middle of stuff)
These issues are far worse on a cold boot, but a warm boot doesn't always fix things.
I have 4 main computers (Plus others, but this is irrelevant). These basic specs for these are:
* Server- A8N-SLI Premium, 3200+, running Ubuntu plus custom junk.
* Desktop- P5N-E SLI, e6320 @ 2.5ghz, 4gb RAM, Win7 Ultimate x64
* HTPC- 6150M2MA, AM2 5000, 2gb RAM, Win7 Ultimate x64
* Laptop- IBM Thinkpad Z61m, Win Vista Pro x64
The only combination which displays issues is the HTPC accessing the server.
I've changed everything under the sun, up to and including a complete hardware & OS change (The HTPC's components migrated into the server & a completely new board was bought).
This is what I've tested:
* Hardware faults- Everything will do a full 24hr run on memtest/ orthos.
* Underlying hardware- This has changed and the issues still persist.
* Operating system- HTPC has migrated from XP to Win7 x64
* Software- Multiple players and filetypes display issues.
* Network- The HTPC works quite happily with the desktop/ laptop, and I can shift which switch the laptop connects to. I've never had any issues with the internet on any computer either.
This is my network topography FWIW:

Thoughts? I'm stumped, and this annoyed me enough last night to try and completely sort it!
