NOTE: After you apply this update, computers on your local Intranet with
completely numeric computer names are treated as if they are in the
Internet zone. Note that Microsoft does not recommend using all numeric
computer names as it can cause some utilities to misinterpret the names
as IP addresses. This is documented in the following article in the
Microsoft Knowledge Base:

TITLE : Use of all Numeric NetBIOS Names Can Cause Problems
To work around this issue if you must use an all numeric computer name,
add the computer's IP address to Internet Explorer's Proxy Server
exceptions list. To do this, use the appropriate method:

address.

- Click Start, click Run, type "ping <all numeric computer name>" where
<all numeric computer name> is the computer's all numeric computer
name, and then click OK.
- Note the computer's IP address, type "exit" (without quotation marks),
and then press ENTER.
- Click Start, point to Settings, click Control Panel, and then
double-click Internet
- Click the Connections tab, and then click Advanced under Proxy Server.
- In the Exceptions box, enter the IP address that you noted in step 2,
click OK, and then click OK.
Microsoft Windows 3.1x or Microsoft Windows NT 3.51
- In Program Manager, click Run on the File menu.
- In Windows NT 3.51, type "cmd" (without quotation marks), and then
click OK. In Microsoft Windows 3.1x, type "command" (without quotation
marks), and then click OK.
- At the command prompt, type "ping <all numeric computer name>" where
<all numeric computer name> is the computer's all numeric computer
name, and then press ENTER.
- Note the computer's IP address, type "exit" (without quotation marks),
and then press ENTER.
- In Internet Explorer, click Internet Options on the View menu, and then
click the Connection tab.
- Click Advanced, and then in the "Do not use proxy server for addresses
beginning with:" box, type the IP address you noted in step 4, click

Reducing Your Risk If You Cannot Apply the Patch
If you are unable to apply the patch, you can reduce your risk of being
affected by this problem by adjusting your Intranet Zone settings to be
the same as those used by the Internet Zone. To do this, perform the
following steps:
- Click Start, point to Settings, and then click Control Panel.
- Double-click Internet, and then click the Security tab.
- In the Zone box, click local Intranet Zone.
- Modify the local Intranet Zone security level or custom settings to
match those in the Internet Zone.
- Click OK to close the Internet Properties sheet.
Note: The default configuration for both the Internet Zone and the local
Intranet zone is "Medium Security". However, there is one difference
between these defaults: the local Intranet Zone enables the automatic use
of NTLM challenge response authentication with local Intranet machines,
while this option is disabled by default when connecting to servers in the
Internet Zone. If you need to change this setting, perform the following
steps:
- Click Start, point to Settings, and then click Control Panel.
- Double-click Internet, and then click the Security tab.
- In the Zone box, click local Intranet Zone.
- Select the level of security that you wish to use under User
Identification | Logon.
- Click OK to close the Security Settings dialog, then click OK to close
the Internet Properties sheet.
