الماسنجر وٍ ISA SERVER

    • هلا فيك،،

      بالنسبة لمشكلتك، فكونك تستخدم ال ISA SERVER و DNS SERVER
      فهذا يدل على انك على تستخدم او على اتصال بشبكة على الأغلب داخلية LAN
      فاذا كان هذا هو الحال! فوجود ال ISA SERVER
      يدل على وضع حظر على بعض صلاحيات المستخدمين من قبل ال Administrator

      حل المشكلة بسيط اذا كنت انت ال Administrator
      فكل ما تحتاج ان تقوم به هو الدخول على ال ISA SERVER
      وتغيير صلاحيات المستخدم اللذي تريده ان يستخدم المسنجر!

      اما اذا لم تكن انت ال Administrator
      فهذا غير ممكن!!



      اما اذا كان المسنجر الذي تستخدمه مركب للاستخدام في نطاق الشبكة الداخلية،،
      ولا يسمح بالدخول على مسنجر الهوتميل مثلا،،
      فيجب ان تعيد تركيب المسنجر وتقوم بتفعيل خاصية السماح باستخدام
      المسنجر الخارجي بالاضافه الى المسنجر الداخلي،،

      على حسب النوع الذي تريد ان تستخدمه،،


      1- عن طريق ال web proxy

      you need to set up a default protocol rule to allow the HTTP protocol, and then add the content group to your HTTP available content types


      a. In the console tree of ISA Manager, click to expand Access Policy, right-click Protocol Rules, and then click New, Rule

      b. In Name, give the protocol rule a name, and then click Next

      c. Click Allow, and then click Next

      d. In Apply this rule to, click to select Selected Protocols, and then in Protocols, select HTTP. Then click Next

      e. In Schedule, click Next to accept the default, or set up a schedule for applying the rule

      f. In Apply the rule to requests from, select Any request, and then click Next

      g. Click Finish to finish creating the new protocol rule

      Once you have created a protocol rule, add the content group:

      a. In the console tree of ISA Manager, click to expand Access Policy, and then click Site and Content Rules

      b. In the details pane, right-click the ISA Server default Site and Content rule, and then click Properties

      c. On the HTTP Content tab, select Specified content groups, and then click New

      d. In Name, type a name for the new content group

      e. In Available Types, type application/x-msn-messenger, and then click Add



      Note If ISA Server requires outgoing Web requests to be authenticated, MSN Messenger 5.0 supports Basic authentication for HTTP. Earlier versions of Microsoft Messenger do not support HTTP authentication

      To enable anonymous authentication for outgoing HTTP requests on ISA Server, in ISA Management, right-click the name of the ISA Server computer, and then click Properties. On the Outgoing Web Requests tab, ensure that Ask unauthenticated users for identification is not checked. In addition, ensure that you either provide an anonymous Site and Content Rule for instant messaging content and destination, or alternatively do not authenticate any requests

      لضيق وقتي،،

    • 2- عن طريق ال SecureNAT Clients

      If the client computer's Web browser is not set up to use ISA Server as a proxy, and you want to configure SecureNAT clients for instant text messaging, you need to set up an access policy rule for the ISA Server MSN Messenger protocol, which is included in ISA Server predefined protocol definitions. Do this as follows


      a. In the console tree of ISA Manager, click to expand Access Policy, right-click Protocol Rules, and then click New, Rule

      b. In Name, type a name for the new protocol rule, and then click Next

      c. Click Allow, and then click Next

      d. In Apply this rule to, click to select Selected Protocols, and then in Protocols, select MSN Messenger. Then click Next

      e. In Schedule, click Next to accept the default, or set up a schedule for applying the rule

      f. In Apply the rule to requests from, select Any request, and then click Next

      g. Click Finish to finish creating the new protocol rule

      Note ISA Server pre-defined MSN protocol definition is a simple protocol definition that defines a primary connection on port 1863, which is the port MSN Messenger and Windows Messenger use for instant text messaging
