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.

Fix: Problem Installing HP OfficeJet 6500 on Windows 7

Problem: 
When trying to install the printer while connected to the network using wire to wireless connection, you get errors during installation process.
if you check your System Event Log  you notice some DCOM errors 10016 saying stuff like this (Hebrew):

‏‏הגדרות ההרשאה המהווה ברירת מחדל של המחשב אינן מעניקות הרשאת הפעלה מקומית עבור יישום COM Server עם CLSID‏ 

{10DA4F3C-CC99-4190-BE4D-58330754E882}

 ו- APPID‏ 

{7DDEFEA6-98EE-4F13-A25B-EC83D9BC5541}

 ל- SID של המשתמש NT AUTHORITY\LOCAL SERVICE‏‏ (S-1-5-19) מהכתובת LocalHost (באמצעות LRPC). ניתן לשנות הרשאת אבטחה זו באמצעות כלי הניהול 'שירותי רכיבים'.

Another example (English):

The machine-default permission settings do not grant Local Activation permission for the COM Server application with CLSID
{10DA4F3C-CC99-4190-BE4D-58330754E882}
 and APPID
{7DDEFEA6-98EE-4F13-A25B-EC83D9BC5541}
 to the user NT AUTHORITY\LOCAL SERVICE SID (S-1-5-19) from address LocalHost (Using LRPC). This security permission can be modified using the Component Services administrative tool.”

On the other hand, it you try to install using a USB connection, everything goes well.
