824684 Description of the standard terminology that is used to describe Microsoft software updates



The hotfix that is described in this article prevents the DNS snap-in from creating new DNS PTR records with uppercase characters. To delete PTR records that contain uppercase characters, or to change uppercase characters in existing PTR records to lowercase characters, install the hotfix that is described in this article. Then, use one of the following methods.

Note These methods use the DNS troubleshooting tool, Dnscmd.exe. Dnscmd.exe is included with the Windows Server 2003 Support Tools in the Support folder on the Windows Server 2003 CD. For information about how to use the Dnscmd.exe tool, click Start, and then locate Support Tools Help in the Windows Support Tools folder after you install the support tools.

Method 1: Delete all PTR records
If you choose to delete all PTR records at the node, use Dnscmd.exe to delete them instead of deleting individual records as described in Method 2. For example, type the following command at the command prompt to delete all PTR records at the 10.3.2.1 address:

dnscmd /RecordDelete 10.in-addr.arpa. 1.2.3 PTR

Important Notice the period (.) after the &quot;in-addr.arpa&quot; string. If you omit the period, you may receive the following error message:

Command failed: DNS_ERROR_ZONE_DOES_NOT_EXIST 9601 (00002581)

Method 2: Convert PTR records that contain uppercase characters
To convert existing uppercase entries, use the following scriptset. This script set includes the following three files:   Capinput.txt

Create this file by using the Dnscmd.exe command-line tool together with the /EnumRecords switch on your Windows 2003-based DNS server. Copy the Dnscmd.exe output into a text file, and then delete the entries that do not contain uppercase characters so that the text file includes only the entries that contain uppercase characters. Save this file as &quot;Capinput.txt .&quot;

Sample Capinput.txt file:  snip begin input file --- 30.1.1 TESTING.department.company.com. snip end input file --- Notice the period at the end of the fully qualified domain name (FQDN).   DeleteDNSNode.bat

This script reads the Capinput.txt file, verifies that the record exists, and then deletes the whole node by using DNScmd.exe to delete the uppercase characters. It also outputs the successfully deleted records to the Input.txt file.

Contents of the DeleteDNSNode.bat file:  snip begin script --- @echo. > input.txt @FOR /F &quot;eol=; tokens=1,2 delims=, &quot; %%i IN (CapInput.txt) DO @call :myloop %%i %%j @goto :eof


 * myloop

@dnscmd /enumrecords 10.in-addr.arpa %1 > NUL @if not errorlevel 1 dnscmd /NodeDelete 10.in-addr.arpa %1 /f & @echo %1 %2 >>input.txt @goto :eof


 * eof

snip end script ---   CreateDNSNode.bat

This script reads the Input.txt file and then re-creates the records by using the DNScmd.exe tool. This script uses the functionality that is provided by the hotfix that is described in this article to change the uppercase characters to lowercase.

Contents of CreateDNSNode.bat: <pre class="fixed_text"> snip begin script --- FOR /F &quot;eol=; tokens=1,2 delims=, &quot; %%i IN (Input.txt) DO dnscmd /RecordAdd 10.in-addr.arpa %%i PTR %%j snip end script --- </li></ul>
