Assume that you try to access a network file share that
resides on a server that is running Windows Server 2003, 2008, or 2008 R2.
However, in this situation, the file sharing connection drops intermittently
after a while, and then the network share becomes unresponsive.
When
this problem occurs, the following events are logged in the event log:
Event ID: 4226
Source: Tcpip
Message:TCP/IP has reached
the security limit imposed on the number of concurrent (incomplete) TCP connect
attempts.
Event ID: 2022
Source:
server
Message: The server was unable to find a free connection
number times in the last
number seconds.
Note Event 2022 may occur every 20 to 30 seconds.
This problem occurs when Windows Server is running certain
versions of Endpoint Protection 11 or Symantec Antivirus 10.2. Some file filter
drivers, such as Srtsp.sys or Srtsp64.sys, may cause this
problem.
To resolve this issue, follow the instructions that are
provided by Symantec to upgrade the software to the latest version of Symantec
Endpoint Protection 11.0.4202.75 (MR4 MP2) or Symantec Antivirus. For more
