for your deployment.
Increase the Size of the TCB Hash Table on a Windows Server Computer
Edit the Windows registry to increase the size of the TCB hash table on a Windows Server computer on which
View Connection Server runs.
Active Directory group policies can override registry entries. When possible, use a group policy to set the size
of the TCB hash table on View Connection Server.

Value Type: DWORD
Value data: calculated hash table size
Valid Range: 64-65536 (decimal)
4 Exit the Windows Registry Editor.
5 Restart the Windows Server computer.
Worksheets for Calculating Ephemeral Ports and TCB Hash Table Size
Use these worksheets to calculate the number of ephemeral ports and the size of the TCB hash table on each
View Connection Server instance and security server in your deployment.
Table 5-13. Configuration Parameters
Configuration Parameters Fill in Your Site's Value
