I-369 If you are having problems with your network since you installed WINS, you can tweak the following registry entries to help improve performance.
Hive: | HKEY_LOCAL_MACHINE |
Key: | System\CurrentControlSet\Services\NetBt\Parameters |
Value Name: | NameSrvQueryCount |
Data Type: | REG_DWORD |
Value: | 3 |
This value sets the number of times that NetBT queries the WINS server before receiving a response.
I-370 | Hive: | HKEY_LOCAL_MACHINE |
Key: | System\CurrentControlSet\Services\NetBt\Parameters | |
Value Name: | Timeout | |
Data Type: | REG_DWORD | |
Value: | 1500 |
This value is the time, in milliseconds, NetBT waits before sending the next query in a series of successive queries.
I-371 | Hive: | HKEY_LOCAL_MACHINE |
Key: | System\CurrentControlSet\Services\NetBt\Parameters | |
Value Name: | SessionKeepAlive | |
Data Type: | REG_DWORD | |
Value: | 3,600,000 |
This value is the interval, in milliseconds, that NetBT waits between sending keep-alive packets for a particular session.
I-372 | Hive: | HKEY_LOCAL_MACHINE |
Key: | System\CurrentControlSet\Services\NetBt\Parameters | |
Value Name: | SizeSmall/Medium/Large | |
Data Type: | REG_DWORD | |
Value: | 1 |
This value regulates the size of the name table, which stores local and remote names. Valid values are 1 = small (16 entries), 2 = medium (128 entries) and 3 = large (256 entries).
You just installed PPTP and are afraid that you may have exposed your network to unwanted attacks. Well, no network is 100 percent secure, but these registry entries let you add a little more security to PPTP.
I-373 | Hive: | HKEY_LOCAL_MACHINE |
Key: | System\CurrentControlSet\Services\RasPPTPE\ Parameters\Configuration | |
Value Name: | AuthenticateIncomingCalls | |
Data Type: | REG_DWORD | |
Value: | 1 |
I-374 | Hive: | HKEY_LOCAL_MACHINE |
Key: | System\CurrentControlSet\Services\RasPPTPE\ Parameters\Configuration | |
Value Name: | PeerClientIPAdresses | |
Data Type: | REG_MULTI_SZ | |
Value: | <valid IP addresses> |
Using these two values, you can effectively control who can access your network via PPTP. If the AuthenticateIncomingCalls value is set to 0, only the clients whose IP addresses match values stored in the PeerClientIPAdresses value are allowed access. If the AuthenticateIncomingCalls value is enabled and no values are contained in the PeerClientIPAddress value, nobody can access your network via PPTP.
