RWW gives error msg: "Invalid server name specified"

We've got a router connected to the Internet (static, pub IP outside, static
private IP inside). SBS has two NICs, "outside" is on same subnet as
router's inside. SBS's inside NIC is on different subnet.

When I connect a laptop via https://mypubip/exchange, I logon and get
e-mail, no problem. When I use https://mypubip/remote, I get a logon, then
the appropriate start page with "connect to servers" link. Clicking on the
link shows the servers that we have, all of which are enabled for terminal
services of either admin or general. Clicking on a computer yields an error
message: "Invalid server name is specified."

All the systems are accessible, and when inside the LAN, RDP works just fine
on them.

Router/firewall is forwarding 4125 and 443 to SBS.

I'm running ISA on SBS. Is there something in ISA that I've neglected to
do? After installing ISA, I ran CEICW and had it issue a cert to our pub IP.
I've installed said cert on the laptop with which I'm trying to connect.

Any thoughts, ideas, and suggestions would be most appreciated.

 

Hi Jim,

Did you use the Add Computer \connectcomputer method to join these servers
to the domain? Static or DHCP? Is the SBS the DHCP server?

Check the actual IP addresses of the servers against what is recorded in
DNS, DHCP, and Wins, and resolve any discrepancies.

 

Hi, Les:

Thanks for the quick response. I did add both servers with
\connectcomputer. Both servers (as well as SBS) have static private
addresses, all in the same subnet. SBS is the DHCP server for the rest of
the network. In DNS, reverse lookup shows the 3 servers (SBS, ENT [TS], and
STD) with their correct IPs.
I don't see them listed in forward lookup, though. Also, I'm not sure where
to find them in DHCP or WINS.

How about if you ping them by name, then, are they answering at the IPs you
expect?

Can you create a RDP connection to them (by name) from a computer on the
lan?

At the DHCP node, expand the scope and look at address leases.
At the WINS node, right click Active Registrations and 'Display Records',
click on the Find Now button.

There must be something out of whack here, we just have to discover what it
is.

You wouldn't have run Spybot on this network, by chance?

This thread appears to indicate an issue on the remote, the workstation you
use to connect *to* RWW.

Hi, Les:

My replies/comments are in-line, below:

It works to ping each by name from a workstation on the LAN. One gets the
expected IP back. I will say, at one point, I thought of using the W2K3 STD
as a secondary DNS, backup DHCP server, along with WINS. But, I've since
demoted it per advice that I've read here in this newsgroup. Some settings
were incorrectly referenced on one or more servers for one or more services.
I've corrected those things, but I haven't had a chance to reboot everything.
I'll do that, soon.

Yes, I can connect to each server from a LAN wkstn by name. Only one system
is a true TS, while the other two (SBS and STD) are set up for admin TS.

Since the servers are static, I wouldn't expect them to show up in here, and
they don't.

One server wasn't listed because it didn't know that the SBS was its
WINS-daddy. I've corrected that, but I'm curious as to why /connectcomputer
didn't input that information when I joined them to the domain.

Regarding the Spybot stuff you reference later; I checked the registry of
the laptop that is my wkstn, and it has no record that such a key existed.
There are A TON of keys in that hive, but none starting with the spybot
active-x blocking RDP bugger.

Nope, no spybot...

One gets the

And two don't?

You could try a few things -

a) post the ipconfig /all from each of the servers, including the SBS - and
we'll have a look.

b) switch the servers to full DHCP and ensure they get a new lease. Grab the
MAC addresses and create reservations for whatever addresses they pick up

c) download, install, and run the SBS Best Practices Analyser - resolve any
issues it reports - and if those issues include advanced NIC features such
as RSS and Task Offloading, check those items on the other servers as well.

 

Hi, Les:

Clearly, the laptop/workstation that I am using is having the problem, not
SBS. I tried logging in from home, where my desktop workstation is. I had
no problem getting to a logon.

Because of the issues mentioned earlier (changes in services running on a
couple different servers), my logon takes a long time as it tries to load
personal settings. This is an AD issue, not a SBS issue, however.

So, the problem originally stated may be an Active-x block caused by some
other software, though I'm not sure how to pinpoint it.

Hi, Les:

So, laptop gives "Invalid server name was specified" when I attempt to use
RWW for remote connections to servers in our SBS domain. I went into IE 6
and found "Manage Add-ons," where, lo and behold, there is a Spybot-SD add-on
for IE. When I go into the registry, however, there is no
HKEYLM\Software\MS\IE\ActiveX-Compatibility\{758xxx. Do you have any
suggestions regarding how to find the key that is associated with Spybot-SD?
I must have loaded it (Spybot-SD) on this system some time ago and removed
it. Any suggestions are greatly appreciated.
There will be several workstations that will require this clean up; if the
HKEY is not as stated in the articles you referenced, I'm not sure I know how
to proceed.

 

I don't have any first hand experience with this issue, your investigation
will be as good as mine.

 

Hello John,

Thank you for posting here.

From your post, I understand that a laptop cannot connect to RWW.

I suggest you try following steps and check if it helps:

NOTE: Please log on the laptop as an administrator.

Suggestion 1: Reset IE settings
=========
1. Click the Tools menu, and then click Internet Options.
2. On the Advanced tab, click Reset.
3. In the Reset Internet Explorer Settings dialog box, click Reset.
4. When Internet Explorer finishes restoring the default settings, click
Close, and then click OK two times.
5. Close Internet Explorer. The changes take effect the next time that you
open Internet Explorer.

Suggestion 2:
=========
Please click Start-->Run, type CMD and click OK. Then run following
commands:

regsvr32 urlmon.dll /s
regsvr32 hlink.dll /s
regsvr32 msjava.dll /s
regsvr32 mshtml.dll /s
regsvr32 jscript.dll /s
regsvr32 vbscript.dll /s
regsvr32 shdocvw.dll /s
regsvr32 browseui.dll /s
regsvr32 actxprxy.dll /s
regsvr32 softpub.dll /s
regsvr32 scrrun.dll /s
regsvr32 shell32.dll /s
regsvr32 Oleaut32.dll /s
regsvr32 wintrust.dll /s
regsvr32 dssenh.dll /s
regsvr32 rsaenh.dll /s
regsvr32 cryptdlg.dll /s
regsvr32 dssenh.dll /s
regsvr32 rsaenh.dll /s
regsvr32 gpkcsp.dll /s
regsvr32 sccbase.dll /s
regsvr32 slbcsp.dll /s
regsvr32 cryptdlg.dll /s
regsvr32 schannel.dll /s
regsvr32 wuapi.dll /s
regsvr32 wuaueng.dll /s
regsvr32 wuaueng1.dll /s
regsvr32 wucltui.dll /s
regsvr32 wups.dll /s
regsvr32 wuweb.dll /s
regsvr32 atl.dll /s
regsvr32 wucltui.dll /s
regsvr32 initpki.dll /s

Suggestion 3:
=========
1. Click Start-->Run, type following command and click OK.

regsvr32 /u "%windir%\downloaded program files\msrdp.ocx"

2. Click Start-->Run, type regedit and click OK.
3. Search for msrdp.ocx, export and then delete all the keys found.
4. Restart the client and check if the issue persists.

I hope the above information is helpful to you. If the problem still
occurs, please help me gather following information:

1. What is the version of IE? IE6 or IE7?
2. On the problematic laptop, try following command and let me know the
result:

telnet pubIP 4125
telnet pubIP 3389
telnet pubIP 443

3. Please download the MPS Report tool from the following link and run it
on both the problematic clients and the SBS server, then send the generated
CAB file to my mailbox for further investigation so
that we can find what the root cause is:

http://download.microsoft.com/download/b/b/1/bb139fcb-4aac-4fe5-a579-30b0bd9
15706/MPSRPT_SETUPPerf.EXE

Please try the above steps at your earliest convenience. If you have any
concern, please feel free to let me know.
