Description
Determines the size of the hash table in which TCP control blocks (TCBs) are stored.
TCP stores control blocks in a hash table so it can find them very quickly. If you adjust the number of TCBs the system creates (as specified by the value of the MaxFreeTcbs entry), you should also adjust the value of this entry proportionately.
Note
The value of this entry must be a power of two. If you change the value, the system rounds the value you enter to the next higher power of two.
Windows does not add this entry to the registry. You can add it by editing the registry or by using a program that edits the registry.
