There is a thread in the Network Management with a question that they cannot access the exchange server through a wireless network. I also, am experiencing this problem. My temporary work-around has been to use Outlook with a POP3 connection. This works, but does not solve the initial problem of being able to connect Outlook using the Microsoft Exchange Server connetion. Here is the link to the other thread.

Has anyone else experienced this problem and has anyone found a solution.

I am supporting a small network which is Win2k with AD. Two DC's, one which is running Exchange 5.5. All workstations on this network can access Exchange just fine. These are Windows 2000 Pro and XP. There is a laptop, running XP and its connection is via a WiFi using 54g. All network network programs, utilities, files, etc are available with this laptop. But it CANNOT connect via the Exchange connection.

Any Ideas would be very helpful.

would you mind telling model numbers of wireless router(s) and something about the configuration and what you have tried? can you ping exchange server over wireless?

by sgt_shultz

have you played with the RIP settings on the wireless router? how about the Exchange connection monitor? what is error? anything in exchange server event logs?

how about the server timeout setting on the clients exchange connector? ok, you are spared anymore of my lame ideas. it is just that i am having weird wireless problems also, not with exchange server. in my case, have a switch connecting an XP pro wkstation and a win98 laptop in bosses home. this little group is connected to main network in house next door via couple linksys wap11's (wireless routers) in bridge mode. win XP machine has no problems doing anything. but win98 pc 'falls off' when boss brings it from home into office and logs onto network in main building. which i don't see how is any different from logging on across the wireless bridge. but somehow it is. can't wait until i understand this one...anyhow, when he brings it back home after logging on at office, it can't logon anymore at home until i 'refresh' the wireless routers. otherwise it fails to find authentication server (yep, it can ping it. it can even pull up router configuration page with internet explorer- just can't authenticate.) i can fix it by accessing each of the wireless routers by ip address with browser (oh, yes, that works on the win98 even when it won't authenticate). i fix it by changging anything each router and resaving the (basically unchanged) configuration (just change anything, then change it back) then the laptops authenticates just fine. huh? when i figure out this one i am going to know a lot more about NT authentication i bet...good luck and thanks for listening (sheepishly)

Thanks for your help. I found the problem. It seems that the WINS table was not complete. When checking it, I noticed that there were only two entries for the Laptop. The one missing was 03h (messenger). I then created a static entry for the computer and the system will now connect to the Exchange server, with no problems at all.

Could your issue, be related to an incomplete WINS table? Just a thought. Anyway, thanks

I am using a Belkin Wireless access point. Model F5D7130. The Laptop is a Compaq 2100 running XP pro. I do not have the specs on the wireless NIC in the Laptop, but it is the one that came with the system when first purchased.

1. I can ping the Exchange server both by IP and by name (server2)
2. The Wireless network is nor readily visible to passing systems, The SSID is hidden.
3. Using 40bit encryption
4. Setup MAC address list for accepted clients
5. Using DHCP form Win2k server.
6. WINS is setup to the same server.
7. There are no errors on the Exchange server. It is like nothing was attempted, so no errors were shown.
8. I have not done anything with RIP. There does not seem to be any setting on the Wireless Access Point that relates to RIP.

Resolution is not a problem. I can resolve to any computer on the network, and any computer on the network can resolve to this laptop. Any and all shares are available to all Nodes. All workstations can ping to any other by IP and by name.

Event log on the XP Laptop, when the Exchange is attempted, only says that there is a time-out and it could not be established.

From 'my chair' it seems like some protocol / port is not being passed across the wireless connection. At least, one that is required by the Exchange server.

Thanks
