Remote Desktop Connection Breaks

I upgraded my Home Theater PC to Vista Ultimate this past weekend; everything
seemed to go OK. I can establish RDC by enabling Network Discovery on the
HTPC and access the machine via RDC from my office PC (Vista U) or my laptop
(Vista HP). All machines are in same workgroup name. But, Network Discovery
gets reset to off for some reason on the HTPC and I cannot connect a cause
with the event. The connection to the HTPC is wireless via Linksys WRT54GS
router and onboard network adapter. I used RDC on the machine before when it
was running WinXPMCE2005SP2, same network, etc. and it never broke. Please
provide some possible causes of Network Discovery being (randomly?) reset to
off.

Thanks,

I would check to see what the network type on the Vista Ultimate (ie. the
old HTPC) machine is configured for, ie. private or public. If this is on
your local LAN make sure its set to private...

If its set for public then Network Discovery, file sharing, etc are disabled
by default.

You might look in the event viewer for possible clues. Also make sure the
Network Location Awareness service is started and set to automatic. If its
failing check the dependencies...

I'm no expert at analyzing the event log but here are events that could be
related. These are Warning level events:
A. Event 4001 (7 occurences in last 24h) WLAN AutoConfig service has
successfully stopped.
B. Event 4226 (2 occurences in last 24h) TCP/IP has reached the security
limit imposed on the number of concurrent TCP connect attempts.

Network Location Awareness Service is Started/Auto
Dependencies:
1. Network Store Interface Service is Started/Auto
.........NSI Proxy Service (I cannot find this in list of services in comp
mgmt)
2. Remote Procedure Call Service is Started/Auto
.........DCOM Service Process Launcher is Started/Auto
3. TCP/IP Protocol Driver (I cannot find this in list of services in comp
mgmt)

Is there any intel in this data?

Not to me...

Does Network Discovery go away in any other case?

This may be a legacy of an upgrade versus a clean install. I hate to say
this but your best recourse may be to blow away the OS and start over fresh.

When I installed Vista U, I did not do the 'upgrade' path to save any
settings, files, etc; they called it a clean install but of course it was
done on the same drive that had the previous OS. Afterwards, once I
determined that all was well, I deleted the old computer stuff after copying
music, pictures, etc. But all apps were installed from new downloads or CDs.
Don't think I'm gonna do that again just to solve this RDC problem since
everything else seems to be working flawlessly. I only use it for music,
movies, and occasional TV recording, so there aren't many apps on it and not
a lot of churn. I drive a front projector with it at 1080p, so I can't use
another local monitor but rely on RDC to do maintenance, rips, etc. There
must be some simple setting that I haven't found yet that will fix this
problem, so I'll keep looking. I am pretty sure that Vista found a new
network adapter driver when it did the windows update scans and I loaded it,
so if the problem persists, I may drop back to the driver that came with the
mobo CD to see if that helps.

!Al, thanks very much for the attention and suggestions!
