Can't Connect Error 80072745

Hi,
I've just installed a Rangemax DG834PN (Wireless Router + ADSL Modem) in a
community centre which supports 13 networked PC's running XP SP2.

12 PC's are connected via an ethernet switch to router/modem and 1 laptop
via wireless. The Internet connection is via a proxy server over ADSL
broadband.
Everything is working wonderfully, full Internet access - wireless and
ethernet.....but, I cannot connect to Windows Live Messenger.

All was fine using a simple Modem interface but installing the router/modem
has disconnected our 'Kid's club' from WLM. I've tried reverting to Messenger
7.4 but I still get the same error message of 80072745
I've enabled/disabled Upnp in the firewall/router/XPSP2 I've tried port
forwarding, several suggested fixes posted here and elsewhere (eg. lower MTU
to 1400, open 443, remove policies from the registry etc.)
The firewall is set to [allow all out] and [disable all in] but even [allow
all in - dangerous, I know] displays the same error.

I've spoken to my ISP/proxy server and they assure me that Messenger is not
blocked by them.
Strange thing is, if I try the built in Messenger test, it says everything
is ok....all connections and ports are fine.

Am I missing something obvoius? Should I be kicking myself? Does anyone have
an answer?

wings...still only had windows messenger 4 days and out of 4 days it hasn't
worked for a single second

Thx guys,
changing the MTU didn't help but starting from scratch using the Connection
Wizard of the router did.
Don't know why, but after running the wizard, I was able to connect to MSN.
All settings appeared the same as I had set them up..................
however, after running the router for about 2 weeks, successfully, the
Internet connection (wireless and ethernet) packed up completely.
I am returning this piece of junk from whence it came and I will not buy
Netgear again!
