Fix: Error: Windows - Low On Registry Space : The system has reached the maximum size allowed for the system part of the registry. Additional storage requests will be ignored.

Symptoms:

On a Windows  XP or Windows  2003  Server you get a warning window giving you the following error message :

Window Title :      Windows – Low on Registry Space

The system has reached the maximum size allowed for the system part of the registry .  Additional storage requests will be ignored.

Problem: 

The main cause is that Windows page-file is corrupted. 

This problem seems to occur in the following circumstances :
– After the installation of Service Pack 2 on Windows 2003 servers.
– After a change of hardware
– And by far the most common occurrence that we have seen is when a change of antivirus software, or a major update to antivirus software, is performed. For example, upgrade from ESET NOD32 v4.2 to v5.0.

For anyone else experiencing this specific “Low on Registry Space” error who does not fall in either of the above two categories, the corruption may have occurred during a power surge or power cut (if your PC is not protected by a UPS), or during a freeze of your PC/server, or, lastly , your hard disk may be going bad and starting to corrupt files and the paging file (if you think it may be the latter, monitor the situation carefully – check, in particular, for NTFS errors in the System log of the Event Viewer).

Solution:

1. Go to the Control Panel.
2. Open the System icon.
3. Choose the Advanced tab.
4. Click  Settings in the  Performance  sub-section.
5. Choose the Advanced tab.
6. Click  CHANGE in the Virtual Memory section.
7. Choose the Advanced tab.
8. Click  CHANGE  in the  Virtual Memory section. You will now see that the paging file has a zero size (shown at the bottom under "Currently allocated")
9. Change the paging file setting to System managed size.
10. Click  SET.
11. Click  OK.
12. At this point you may be asked if you want to overwrite the old paging file  - Answer YES !
13. Click OK all the way out back to the Control Panel.
14. You may or may not be asked to reboot your computer.  Reboot anyway.

That’s it.

Fix: Outlook Error "Sending reported error (0x800CCC13) : ‘Unable to connect to the network. Check your network connection or modem"

Known fix:
Delete the mail account from the active profile.
Re-create the mail account. That's it!
I've came across this problem under Windows XP(SP3) + Outlook 2010 using POP3 account.

Other possible fixes:

Start the Office program in safe mode
1. Click Start, point to All Programs, and then point to Microsoft Office.
2. Press and hold the CTRL key, and then click the Outlook Application.

If the problem does not occur in the safe mode, this issue might be related to some third-party add-ins in the Office program, we can try to disable them. Normally, you could do the following to disable the conflict add-ins in your Office program:

Disable add-ins
a) Click File menu, click Options > Add-in, click Go button in the Manage: Com-in Add.

b) Check if there are any add-ins, clear the checkbox to disable them.

c) Close the Office program and restart it.
d) Add one check back each time to the list of Add-In, restart the Office program, and repeat the above procedure. Once the issue reappears again, we can determine which add-in causes this problem and then disable it.
