This one is killing me on one SBS server I have.
An existing SBS Server which has been running for about 2 years..and RWW was working great up until recently. Now, when one VPNs into their network..and logs into RWW...selects the computer they wish to remote into..this error comes up:
VBScript:Remote Desktop Disconnected
The client could not establish a connection to the remote computer. The most likely causes for this error are:
1) Remote connections might not be enabled at the remote computer.
2) The maximum number of connections might be exceeded at the remote computer.
3) A network error might have occurred while establishing the connection.
4) The Remote Web Workplace designated port might be blocked by a firewall.
Now...it works internally..if I go to one of the workstations on their network...go to the RWW site...and select another workstation or a server...it RDP comes up fine.
But if I come into their network from the outside...I VPN in...it will not work anymore..that error comes up as soon as I select the PC to RDP into and click the Connect button.
However..doing a direct RDP session always works. This is the interesting part.
The server is an HP Proliant DL380 G5, SBS2K3 R2 Standard Edition. Single NIC.
So 3rd party software firewalls.
I do not have any services available to the outside world...all of their staff must VPN in before pulling up RWW or OWA. The VPN device is a Juniper SA700 SSL VPN appliance..it's been in production for over 2 years now, and has worked great. At the time the RWW issues surfaced..nothing had changed on the Juniper appliance. I upgraded the IVE (firmware) last night to the latest version just to see if it would fix the issue..nada.
The network is all on a single IP range..10.1.1.xxx, no VLANs or anything like that.
Server had Sharepoint reinstalled due to a botched "upgrade" attempt to Sharepoint 3..before I had found the proper way to do a parallel install of Sharepoint 3.
Server is running the newer WSUS.
In researching this issue...I found one person that had a similar issue..his DHCP had gone crazy and had too many stale leases. So I went in and shortened the lease time, as well as removed a bunch of stale leases, restarted DHCP service...no luck. The network is nearing 70 users..approx 30 of which are laptops users coming in and out several times a week.
Another find I stumbled across while researching was a mention of improper MTU on the firewall...I double checked that..they're on business class cable, a 10/2 connection, it's properly set at 1500 and I checked that with online tests. Firewall has also been in place for a over a year now..and it had been running fine through it.
I've rerun the CEICW many times.
I've run the BPA many times and followed the suggestions.
