SYMPTOMS
========
In some situations, it may be difficult to establish a Remote Control session
with a Windows NT system that contains more than one network adapter. These
multihomed systems add a certain degree of complexity to the process required to
establish a remote control session.
Please note that Microsoft is working to develop solutions to the variety of
issues that result from the added complexity of multihomed systems. In some
cases, hotfixes have been developed to resolve these issues. The workarounds
described in this article should be tried as a last resort.
On multihomed systems, it is not uncommon for the Systems Management Server
Remote Control agent to "listen" on a IP address that is different from the IP
address that was reported in the Systems Management Server inventory. When this
occurs, an attempt to establish a remote control session may fail with the
following message:
Unable to locate <machine name>.
To establish any remote control session, it is necessary for the Remote Control
agent (Wuser32.exe) to listen on one of the "network paths" that the Systems
Management Server Administrator program will attempt to use. To achieve this,
you can either make changes to the way the Remote Control agent functions
(client side) or make changes in the way that the Administrator program locates
the client (administrator side).
The actual change that you should make depends on the network environment and the
configuration of the client you are attempting to remote control.
WORKAROUND
==========
To work around these problems, try any one of the following (each workaround is
described in more detail below):
- Apply Systems Management Server 1.2 Service Pack 3.
- Configure the Remote Control agent to use a NetBIOS session.
- Manually override the IP address reported by the Systems Management Server
inventory.
Apply Systems Management Server 1.2 Service Pack 3
--------------------------------------------------
Systems Management Server 1.2 Service Pack 3 contains an enhancement that allows
the Administrator program to perform NetBIOS name resolution to locate the
Systems Management Server client if the IP address in the Systems Management
Server database fails to locate the client successfully. Try installing the
service back before attempting the other workarounds.
In a situation where the IP address in the database fails to successfully
establish a remote control session, the Administrator program will query on the
NetBIOS name registered by the Remote Control agent. This name appears as
"machine name <43h>" in the WINS database.
To gain this functionality, you must run the service pack setup on the same
system that is running the Administrator utility. Doing this updates the Systems
Management Server Administrator program on that system.
Configure the Remote Control Agent to Use a NetBIOS Session
-----------------------------------------------------------
By default, the Remote Control agent is configured to use IP sockets for a remote
control session. You can use the Administrator program to configure this
site-wide setting. To view these settings, open the Site Properties window,
click Clients, and then click Options.
NOTE: You must upgrade the Systems Management Server client on computers running
Windows NT to propagate any changes made to the Remote Troubleshooting Options
screen. You can do this by running Upgrade.bat from the SMS_SHR share on a
Systems Management Server logon server.
It is possible to override these site-wide settings on a per-client basis by
changing a registry value on the client you are attempting to remote control.
Before changing this value, it is necessary to determine which Lana number (a
NetBIOS network path) would be suitable for a Remote Control session.
I. View the Lana numbers defined on the client computer running Windows NT.
1. Open Control Panel Network.
2. From the installed services, select the NetBIOS Interface, and then click
Properties.
From the list of defined Lana numbers, you may see something like "NetBT - >
El90x -> El90x1" defined for Lana 0. This can be interpreted as NetBIOS
encapsulated in TCP/IP over the Ethernet adapter. This is normally the most
desirable choice for a remote control session. As long as a name resolution
method (such as WINS) is being used in the network environment, this is a
reliable choice.
NetBT = NetBIOS encapsulated in TCP/IP
NwlnkNB = NetBIOS encapsulated in IPX
NBF = NetBIOS encapsulated in NetBEUI
For systems that use a dial-up connection as well, other Lana numbers may appear
something like "NetBT -> NdisWan4".
II. Configure the Remote Control agent to listen on a specific Lana number.
1. Open the Registry Editor (Regedt32.exe) and find the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SMS\Client Services
\Remote Control\Parameters
2. Change the "CommandLine" value from "-IP" (IP Sockets) to "-L0" (Lana 0). To
permanently override the site-wide setting, set the "Override Site
CommandLine" value under the Remote Control key to a value of "1" as well.
This ensures that the CommandLine value is not overwritten if the Systems
Management Server client components are ever upgraded.
NOTE: Another option would be to set the CommandLine value to "-IPX". This forces
a remote control to occur over NWLink IPX/SPX Compatible Transport.
Manually Override the IP Address Reported by the SMS Inventory
--------------------------------------------------------------
In some situations where it is absolutely necessary to establish a remote control
session over IP sockets, it is possible to replace the IP address normally
inventoried by Systems Management Server with the one that the remote control
agent is listening on.
I. Determine which IP address the Remote Control agent is listening on.
1. At the Systems Management Server client, start the Help Desk Options utility.
You will see the following message at the bottom of the window:
WUSER is listening on TCP/IP address xxx.xxx.xxx.xxx
2. Verify that this is NOT the IP address that is recorded in the Systems
Management Server database for this client. If it is, no further action is
required.
3. Cut and paste the following text into a Notepad text file. The file should
begin with the "Start Component" statement on the first line and end with
"End Component" on the last line.
Start Component
Name = "Machine"
Start Group
Name = "Network"
ID = 1
Class = "MICROSOFT|NETWORK|1.0"
Start Attribute
Name = "Network Active"
ID = 1
Access = READ-ONLY
Storage = SPECIFIC
Type = Int
Value = 1
End Attribute
Start Attribute
Name = "Major Version"
ID = 2
Access = READ-ONLY
Storage = COMMON
Type = Int
Value = 3
End Attribute
Start Attribute
Name = "Minor Version"
ID = 3
Access = READ-ONLY
Storage = COMMON
Type = Int
Value = 5
End Attribute
Start Attribute
Name = "Network Type"
ID = 4
Access = READ-ONLY
Storage = COMMON
Type = String(64)
Value = "Microsoft Windows Network"
End Attribute
Start Attribute
Name = "IPX Address"
ID = 5
Access = READ-ONLY
Storage = SPECIFIC
Type = String(24)
Value = "[IPX address]"
End Attribute
Start Attribute
Name = "IP Address"
ID = 6
Access = READ-ONLY
Storage = SPECIFIC
Type = String(20)
Value = "[IP address]"
End Attribute
Start Attribute
Name = "Subnet Mask"
ID = 7
Access = READ-ONLY
Storage = COMMON
Type = String(16)
Value = "[subnet mask]"
End Attribute
Start Attribute
Name = "Default Gateway"
ID = 8
Access = READ-ONLY
Storage = COMMON
Type = String(16)
Value = "[default gateway]"
End Attribute
Start Attribute
Name = "DNS Machine Name"
ID = 9
Access = READ-ONLY
Storage = COMMON
Type = String(128)
Value = "[DNS name]"
End Attribute
Start Attribute
Name = "LogOn Name"
ID = 10
Access = READ-ONLY
Storage = COMMON
Type = String(48)
Value = "[logon name]"
End Attribute
End Group
End Component
4. Enter the correct values for all of the attributes. Remove all the brackets
from inside the double quotation marks. For example, the IP Address value
should look something like:
Value = "123.45.67.89"
NOTE: If any of the defined attributes are removed from this file, its
corresponding value in the Systems Management Server database will appear as
"null".
5. Save the file with the name Network.mif (the name is flexible, but it must
end with a .mif extension).
6. Copy the Network.mif file to the Ms\Sms\Noidmifs directory on the client
computer.
The next time this server is inventoried, this Noidmif file will be appended to
its normal inventory and will override the IP address that is normally
collected. This should allow a remote control session to be established.
