I-415 You must also change this registry entry to disable VJ compression:
Hive: | HKEY_LOCAL_MACHINE |
Key: | System\CurrentControlSet\Services\RasMan\IPCP\ Parameters |
Value Name: | AcceptVJCompression |
Data Type: | REG_DWORD |
Value: | 0 |
You must restart RAS for this change to take effect.
I-416 If you want to keep track of who is using your RAS server by having RAS write in the Event Log, change this entry.
Hive: | HKEY_LOCAL_MACHINE |
Key: | System\CurrentControlSet\Services\RasMan\ Parameters |
Add the following value under the Parameters key:
Value Name: | Logging |
Data Type: | REG_DWORD |
Value: | 1 |
I-417 You recently established service with an ISP. The problem is, you can ping the LAN before you dial up your ISP, but not after. Modify these registry entries to fix this problem.
Hive: | HKEY_LOCAL_MACHINE |
Key: | System\CurrentControlSet\Services\RasMan\PPP\IPCP |
Add the following value under the IPCP key:
Value Name: | PriorityBasedOnSubnet |
Data Type: | REG_DWORD |
Value: | 1 |
I-418 | Hive: | HKEY_LOCAL_MACHINE |
Key: | System\CurrentControlSet\Services\RasMan\ Parameters\PPP | |
Value Name: | Logging | |
Data Type: | REG_DWORD | |
Value: | 1 |
This value controls the logging action of PPP events that the RAS server handles. A value of 1 enables logging and 0, the default, disables logging.
I-419 If you recently added Internet access to your LAN via the RAS server and can get out just fine but everything coming back stops at the default gateway machine, then change this registry entry.
Hive: | HKEY_LOCAL_MACHINE |
Key: | System\CurrentControlSet\Services\RasArp\ Parameters |
Add the following value under the Parameters key:
Value Name: | DisableOtherSrcPackets |
Data Type: | REG_DWORD |
Value: | 0 |
Now all your Internet data will make it back to the right machine.
I-420 Are you having problems with your dial-up connections? Are you getting more retries than you should? You may need to enable the FIFO buffer on your serial card (if you have one, and you should). In addition, you may want to lower the receive buffer. These registry entries let you govern the size of the FIFO buffer for both receiving and transmitting.
Hive: | HKEY_LOCAL_MACHINE |
Key: | System\CurrentControlSet\Services\Serial: |
Value Name: | ForceFifoEnable |
Data Type: | REG_DWORD |
Value: | 1 |
Enable the FIFO buffer by setting this value to 1. Restart the machine and see if this helps. If you still experience problems, try reducing the value of the receive FIFO buffer to 4; if you still have problems, drop it to 1.
I-421 | Value Name: | RxFIFO |
Data Type: | REG_DWORD | |
Value: | 4 |
This value governs the receive buffer.
I-422 | Value Name: | TxFIFO |
Data Type: | REG_DWORD | |
Value: | 8 |
This value governs the transmittal buffer.
I-423 Have you noticed that your laptop seems to receive files when youre connected to the corporate Ethernet but chokes when youre connected at a lesser speed (i.e., on a 28.8 modem connection)? Try modifying this parameter.
Hive: | HKEY_LOCAL_MACHINE |
Key: | System\CurrentControlSet\Services\TCPIP\ Parameters |
Add the following value under the Parameters key:
Value Name: | TcpWindowSize |
Data Type: | REG_DWORD |
Value: | 8192 |
Generally, slower connections benefit from a higher value; however some RAS connections work better with the value set to around 2768. For maximum efficiency, this value should be an even multiple of the TCP maximum segment size.
