Tcp concurrent connection limit in sp2
Does anyone know how to remove the security limit imposed
my xp sp2 on the number of concurrent tcp connections? sp2 causes some of my programs to error with the error # 10055 because of this new limitation sp2 implements. |

You're talking about file sharing. SP2 does, in fact, limit TCP connections
in order to prevent trojans from distributing themselves - I remember reading that somewhere on MS site. "Carey Frisch [MVP]" wrote in message ...

Tcp concurrent connection limit in sp2
I knew I've seen it somewhere.
"The TCP/IP stack now limits the number of simultaneous incomplete outbound TCP connection attempts. After the limit has been reached, subsequent connection attempts are put in a queue and will be resolved at a fixed rate. Under normal operation, when applications are connecting to available hosts at valid IP addresses, no connection rate-limiting will occur. When it does occur, a new event, with ID 4226, appears in the system's event log." http://www.microsoft.com/technet/pro...on127121120120 "Carey Frisch [MVP]" wrote in message ...

Yes, but notice this DoS attack feature is not the same as the
hard limit on simultaneous connections that NT family non-server version have always had. The DoS attack rate-limitiing feature is distinctly different and it can be relaxed. -- Roger Abell Microsoft MVP (Windows Server System: Security) MCDBA, MCSE W2k3+W2k+Nt4 "Fritz" wrote in message ...
