The MAC address for the Windows guest seems odd. The Xen Wiki recommends:
- ---
Virtualised network interfaces in domains are given Ethernet MAC
addresses. By default xend will select a random address, this will
differ between instantiations of the domain. If it is required to have a
fixed MAC address for a domain (e.g. for using with DHCP) then this can
be configured using the mac= option to the vif configuration directive
(e.g. vif = ['mac=aa:00:00:00:00:11']).
When choosing MAC addresses to use, ensure you choose a unicast address.
That is, one with the low bit of the first octet set to zero. For
example, an address starting aa: is OK but ab: is not. It is best to
keep to the range of addresses declared to be "locally assigned" (rather
than allocated globally to hardware vendors). These have the second
lowest bit set to one in the first octet. For example, aa: is OK, a8: isn't.
In summary, an address of the following form should be OK:
XY:XX:XX:XX:XX:XX
where X is any hexadecimal digit, and Y is one of 2, 6, A or E.

(The full article is here: http://wiki.xensource.com/xenwiki/XenNetworking)
Your MAC starts with 11 - 00010001 in binary, which makes it a multicast
address (I think). Starting it with 12 would give 00010010, which I
think should be fine. The MAC on the RH guest starts 00, which is also
unicast, but I don't think its defined as a locally administered MAC.
So far, that's the only thing I've noticed that could be problem.
I'd suggest trying changing the MAC and seeing if that has any effect.
