With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing

As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

Problem configuring ISA for Blackberry Enterprise Server connection

Asked by Vision_Globale in MS Forefront-ISA, Windows 2003 Server, Blackberry Operating System

Tags: , , ,

Hi everyone,

I've been looking at a solution for a couple of days now and i'm not able to find an answer, so i hope you guys can help me.

My Blackberry server is in my internal network behind the ISA server 2004.

I created an access rule :
Allow Port 3101 from my BES server to *.blackberry.net (srp address) for all users.

I saw a couple of discussions saying that it only needs that to work.  However, it doesnt.

I received the following error :
Denied Connection - A non-SYN packet was dropped because it was sent by a source that does not have an established connection with the ISA Server computer.

So, my Bes server is able to send the 1st request to the srp.na.blackberry.net but not the second or third...

Initiated Connection at 23:05:18
Log type : Firewall service
Status : The operation completed successfully
Rule : Allow Blackberry
Source : Internal (x.x.x.x:2300)
Destination : External (srp.na.blackberry.com 204.187.87.33:3101)
Protocol : Blackberry

Denied Connection at 23:05:26
Log type : Firewall service
Status : A non-SYN packet was dropped because it was sent by a source that does not have an established connection with the ISA Server computer.
Rule : -
Source : Internal (x.x.x.x:4982)
Destination : External (srp.na.blackberry.com 204.187.87.33:3101)
Protocol : Blackberry

I know it's not an issue on my blackberry server because it works if it's not behind the ISA.

Thank you to help me with this huge problem!Start Free Trial
