Unable to see iTunes libraries bi-directionally on MBP 17"

Question

Ok, I've got an odd situation that I can't figure out. (I also posted this in the Bonjour Windows forum as well, but figured I might get help here as well) Here's the background information:
1) Home network consists of 2 routers. Router 1 (a Buffalo with 802.11g, running dd-wrt) is plugged into the cable modem. It's the DHCP server, assigning addresses in the 192.168.1.0/24 block. It broadcasts 2.4GHz with SSID = NET1. Router 2 is a Linksys WRT320N running dd-wrt, connected to router 1 as a simple switch (devices connected to router 2 get IPs assigned from router 1). It broadcasts on the 5GHz band as SSID = NET2.
2) Dell desktop (running Win 7 Home Premium x64) is connected to router 2. MacBook Pro 17" (running Snow Leopard) is connected to router 2 via wireless. There's also a NAS (Synology) connected to router 2. Other devices in the house (including an older Airport Express, vonage box, etc.) are connected wired/wireless to router 1. Again, everything is in the 192.168.1.0/24 network.
3) When I fire up iTunes on the desktop, it can see the iTunes library on the MBP, connected wirelessly to NET2. The opposite is not true (and yes, I have sharing enabled). Software firewall is off on the MBP and PC. Additionally, the MBP cannot see the Airport Express speakers on NET1.
As an aside, I can manually connect to network shares on the desktop from the MBP by doing a Cmd-K in Finder. Once I've connected, the machine will show up in the Shared list in Finder, but still no iTunes Library.
4) If I switch the MBP to connect wirelessly to NET1 (router 1), it can see the Airport Express speakers, but still not the iTunes library on the Desktop.
Any idea what the deal is?

Hi
Even if i use a new clean blank rtf doc as the template, it still doesnt write out a file.
When i look in the log directory at the .out files produced, they look right. If i open the .out file with Adobe Reader 9.1, the doc looks exactly as it should. It just doesn't write the file to the destination folder specified.
It cannot be permissions as it will write out RTF/excel files to the same directory with no problems. The report is using a bursting definition but the problem cant be that because it bursts the data correctly, as shown if i specify rtf output in the bursting definition/as shown by the .out files when i specify pdf as the output in the bursting definition. Also, i get the same result even if i schedule any other report that does not use a bursting definition.
I do get an error sometimes when i try to open pdf reports : Cannot use Adobe Reader to view PDF in your web browser. I feel somehow that this may be related and that if i fix this, i could be sorted, but im not even sure im on the right track here.
Im really really REALLY at wits' end here, ive been trying to solve for weeks, but just cant figure it out. Any further ideas would be most welcome, thanks.
