Status: Verified
SYMPTOM(s):
All Client connections are slow
All Client processing is slow
Stopping NT Remote Access Server (RAS) and rebooting the server, does not improve performance for the LAN client Progress Application users
Setting NTRAS to "manual" and rebooting the server, did not have any effect on the LAN client Progress Application users.
FACT(s) (Environment):
LAN performance degradation
TCP/IP protocol
Windows
Progress 8.x
Progress 9.x
Progress 7.x
CHANGE:
Installed NT Remote Access Server (NT RAS) on same box as Progress
CAUSE:
Installing NT RAS allows remote users to connect to the network, via a modem, as if they were directly connected via (say) TCP/IP.
After installing NT RAS, the binding paths for services | protocols | adapters are modified. These will be processed in the order listed in the Network settings.
It is possible that this will result in the device that the binding path is connected to first, is a modem device instead of the network interface card. This will have a marked effect on performance of LAN users as each modem device will be checked first (with waits) before eventually getting to the Network interface card (at the bottom of the list)
FIX:
To verify the order of the bindings:
WINNT: Network Neighborhood -> [right click] -> Properties -> Bindings -> "Show Bindings for" = "all protocols"
Ensure that the Network interface card is the first binding path in the list below the protocol in use (TCP/IP) and adjust as necessary using the [Move Up] [Move Down] buttons.
Binding paths are processed in the order listed, so as a general rule:
- Protocols used most frequently should be placed first in the list to reduce connection time.
- If some protocols are faster than others, putting the faster protocol first in the binding list can also improve performance.
