· Filed under Exchange 2003, windows ·Tagged Undeliverable error on exchange 2003, Undeliverable:
Few days ago I got a error of undeliverable message on exchange 2003.
Undeliverable error
Possible Cause:
- The e-mail account does not exist at the organization the message was sent to. This issue may occur if there was a problem when users were moved between sites. For example, if a former Administrative_Group_1 user moves to Administrative_Group_2 and then replies to an old e-mail message, or if the user does not re-create his or her Outlook profile, an old Administrative Group style LegDN address will be used, and an NDR is generated.
- The message was sent to obsolete personal address book entries.
- The categorizer rejected delivery because you configured your SMTP contact with see comment SMTP RFC821 characters.
Troubleshooting: Verify the recipient address and resend the message. Verify that the recipient address is formatted correctly and that the categorizer was able to correctly resolve the recipient.
After resending to proper recipient I got the problem solved.

· Filed under windows ·Tagged .net error, An unhandled exception has occured
Few days ago I got the following error on a pc.
The problem occurs because Microsoft Data Access Components (MDAC) is not installed on the computer. The .NET application uses MDAC to access the data from the database.
To resolve this problem, I installed MDAC on the computer. I downloaded MDAC from the following Microsoft Developer Network (MSDN) Web site:Data Access downloads
http://msdn2.microsoft.com/en-us/data/aa937695.aspx
And now the problem is solved.

· Filed under windows ·Tagged Adjusting TCP MTU, RDC gets hanged, RDC problem, Tuning TCP Tuning
Few days ago, I faced problem at remote desktop connection. I could could connect to the remote pc through RDC but it was getting hanged after logging in. Later we found that there was change at remote server at firewall. I had to change adjust the TCP MTU to 1300 to get the connection properly. To adjust the TCP MTU I had to do the following things.
To modify the PPPoE MTU size, create the following registry key:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Ndiswan\Parameters\Protocols
Then add the following registry entries.
Collapse this tableExpand this table
| Entry name |
Data type |
Value data |
| ProtocolType |
REG_DWORD |
0×00000800 |
| PPPProtocolType |
REG_DWORD |
0×00000021 |
| ProtocolMTU |
REG_DWORD |
the appropriate MTU size (in decimal) |
To do this:
- Click Start, click Run, type regedit, and then click OK.
- Locate and then click the following key in the registry:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Ndiswan\Parameters
- On the Edit menu, point to New, and then click Key.
- Type Protocols, and then press ENTER.
- On the Edit menu, point to New, and then click Key.
- Type 0, and then press ENTER.
- On the Edit menu, point to New, and then click DWORD Value.
- Type ProtocolType, and then press ENTER.
- On the Edit menu, click Modify.
- Type 800, and then click OK.
- On the Edit menu, point to New, and then click DWORD Value.
- Type PPPProtocolType, and then press ENTER.
- On the Edit menu, click Modify.
- Type 21, and then click OK.
- On the Edit menu, point to New, and then click DWORD Value.
- Type ProtocolMTU, and then press ENTER.
- On the Edit menu, click Modify.
- Type the appropriate MTU size (decimal value), and then click OK.
Tuning TCP MTU image 1
- 19. Browse to the TCP/IP registry keys under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parametersby expanding successive folders on the left panel and scrolling down as needed.
- Create a MTU value according to this.
MTU
Key: Tcpip\Parameters\Interfaces\interfaceGUID
Value Type: REG_DWORD—number
ValidRange: 88–the MTU of the underlying network
Default: 0xFFFFFFFF
Adjusting TCP MTU at client pc image 2
Description: This parameter overrides the default Maximum Transmission Unit (MTU) for a network interface. The MTU is the maximum IP packet size, in bytes, that can be transmitted over the underlying network. For values larger than the default for the underlying network, the network default MTU is used. For values smaller than 88, the MTU of 88 is used. I insert the MTU value 1300.
And Finally I could log in at the remote server through RDC successfully.
Actually I do not know much about this. Any comment or suggestion regarding this topic will be highly appriciated. Waiting to hear from you.

· Filed under windows ·Tagged Command not available at outlook office assistant, outlook office assistant, outlook office assistant error
Today , one of my client faced a problem. While he was clicking on the “out of office assistance” at tools option he was getting an error message telling “Command not available. See the program documentation about how to use extension“.
I have solved the problem very easily (but it took some time, as I faced it first time) on the following way.
1. Open Outllook.
2. Click Help.
3. Click About Microsoft Outlook.
4. Click on Disable Items Entry.
5. There I found “Addin: outex.dll (outex.dll)“. Click on it to highlight it and then click on the Enable Button.
6. Then Click on the Close button.
7. Then click on the OK button to close the About Microsoft Office Outlook.
That’s all. We can do this on another way.
1. Quit Outlook if it is running.
2. Press CTRL+ALT+DELETE, and then click Task Manager.
3. On the Processes tab, verify that Outlook.exe does not appear in the list of processes. If it does, click Outlook.exe and then click End Process.
4. On the File menu, click Exit Task Manager.
5. Click Start, and then click Run.
6. In the Open box, type regedit and then click OK.
7. Locate and then click the following registry key:
HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Outlook
8. Right-click the Resiliency subkey (if it exists), and then click Rename.
9. Type Resiliency.old, and then press ENTER.
10. Quit Registry Editor.
11. Start Outlook, and then click Out of Office Assistant on the Tools menu.
That’s all. Hope to get comments from the readers.

· Filed under Networking, Servers, windows ·Tagged Active directory, Hiding desktops on a domain
Yesterday I got a problem of hiding desktop on a domain. Many companies do this at their domain. We can do these using active directory group policy. To do such things we can follow the following steps on your AD server.
1. Click Start, click Run, and then type gpedit.msc.
2. Under Local Computer Policy, expand User Configuration, expand Administrative Templates, expand Desktop, and then click Active Desktop.
3. Double-click Active Desktop Wallpaper.
4. On the Setting tab, click Enabled, type the path to the desktop wallpaper that you want to use, and then click OK.
I worked like this on my domain. The server OS is Windows 2003 server.
Hope that it may come useful to you. I need your suggestion and tips regarding active directory as I am a new at windows AD.
