Ping command…..needs to close

I had a client today advise they were unable to send or receive e-mail using Outlook.  Upon initial inspection this was the case and Outlook showed as disconnected (using Exchange).  There were no other obvious issues, web browsing and all network services “seemed” to be working properly.  However, there were frequent pop-ups with the message:   

TCP/IP ping command has encountered a problem and needs to close

Pinging did work fine, for the record. While doing a quick search for possible solutions I came across many others with a similar problem, so I thought I would take a moment to post my findings. 

The Event logs had additional errors the key one being:  Event ID: 4226,  Source: Tcpip,  TCP/IP has reached the security limit imposed on the number of concurrent TCP connect attempts.

Though there could be other causes, this usually indicates some sort of malware, as confirmed by 

Kaspersky’s Anti-rootkit utility TDSSKiller located 2 viruses, and AVG a third as shown in the image below. Keep in mind other viruses could present themselves in the same way.  Clearing all temp folders and a full scan by multiple other malware detection apps did not reveal any other issues, but one must always be concerned that “once infected, always suspected”.   Outlook now worked properly with no repairs required to the application or networking.


Cannot open the Outlook window. Invalid XML

I recently came across an instance of Outlook 2007 which would not open.  A popup reported; “Cannot start Microsoft Office Outlook. Cannot open the Outlook window.  Invalid XML, the view cannot be loaded”.  This was only occurring on 1 PC, for one user, in an SBS 2008 environment.  If the user ran Outlook on another PC, there was no problem so it was obviously a local problem.  Doing a repair install of office did not resolve, nor did the diagnostics suggested when Googling the issue.  Assuming it was a problem with the Xml file; I closed Outlook, renamed the Outlook.xml file (safer than deleting), and restarted Outlook to find the problem was resolved.  Should you wish to try the same solution, the file path with Office 2007/2010, on Vista\Win 7 is C:\Users\<user name>\AppData\Roaming\Microsoft\Outlook\Outlook.xml   You will need to enable “Show hidden files, folders, and drives” and “Hide extensions of known file types” to view.
