Can I restrict or limit internet access on a farm in RDS?

Location:
-need to allow remote access to the farm of RDS Internet of remote sites (without VPN)
-Sessions close require access to the intranet using IE (Dynamics CRM)
-Some users do not use internet in a responsible manner (wasting time, inappropriate sites, etc.)
-need ability to prevent browsing of the sessions

I know that we could set up a proxy server (IAS or similar) at Headquarters but I can't handle this being rather long and frustrating for users (and so myself).  I have also no prior experience in the implementation or management of a proxy server (just to know that they can cache and filter web site traffic), so one for 300 active users on the portal management would be a problem.

If I want to avoid using a proxy server at Headquarters can I do a GPO or something to prevent casual internet browsing from just the servers in the farm?  If we can allow access to specific sites (white list) which would be an interesting option, but not a condition in this regard.

We review to implement a form of filtering on remote sites affected (using K9 agents on computers personal or similar) of the internet, so we should just remove the back door of the use of the farm to browse the internet and circumvent the once connected local filtering.

Remote sites use stations XP and Win7, configured in mode working group.  Each site has 2 to 4 computers.  Remote sites share their internet access with computers not relating to staff, so we are reluctant to restrict internet access for all users on the site (using the subscription services provider of firewall for example).  There are more than 20 remote sites.

The farm is built using the 2008r2sp1 server.  We have a RDS (also a dedicated redirector) gateway and 4 session host servers.

Any ideas?

    2. It is an internet connection wired or wireless?
    3. Are you able to connect any other device to the same router and internet access?

    Some common problems that can cause these problems are:

    1. a wireless network adapter switch that is not enabled.
    2 WEP, WPA or WPA2 key or password security issues.
    3. the cables that are not connected correctly.
    4. the corrupt or incompatible drivers.
    5. missing updates.
    6. network connection settings.
    7. hardware or software problems.

    See the methods mentioned below and try to update the drivers that is mentioned in the link

  • What product can hunt an internal user internet access web site?

    Dear all,

    My client uses ASA 5512, they want to check and record their internal users (employees) visited this site web (HTTP, HTTPS, FTP etc.).

    I have not a clue what cisco product or other reason.

    THX

    The module of firepower on the ASA 5512 - X, when licensed and configured with an appropriate policy, can do this.

    The ASA 5512 - X by itself cannot.

    If you can share "inventory" and "module" we can get some clues on the preparation and the ability to run the module of the unit. We would look for the required and installed SSD sfr module type.

  • LAN/Ethernet and wireless: can connect to networks, but shows "no Internet access.

    My workplace has cable/Ethernet and Wi - Fi.  I'm working on a laptop, plug it into a dock where my ethernet cable is connected.  Lately, I've been the startup object and the network will connect automatically (by default to connect to the local network, not for the wireless) but I get the point of the triangle/yellow exclamation on my network icon and displays "no Internet access.  Even if I get this warning message /, in fact, I can access the internet, but I can't access resources online through a program installed (such as, to access to the / insertion of a photo online by word or update a SharePoint Outlook calendar).

    In the past, I could connect wirelessly and work around this problem.  However, now my wireless connection does the same thing: it will connect, it displays the warning "no access Internet, I can access the internet, but not another program."

    I ran the resolution of problems and it does not identify the problem.  I've updated drivers, disconnected and reconnected networks - nothing seems to work.  Any ideas?

  • How can I find an agent I chatted with that? The email with a link that he sent said my e-mail address is not in the folder, and my computer doesn't have internet access once it has access to my office.

    I had the technical support to help me access the internet.  It was slow in response and doesn't seem to understand what I needed.  Invited access to my office, and at that time, I was tired of him saying the same thing over and over again, so I went offshore.  Then I found that my computer doesn't have internet access either.  I tried to find him, found the email that he sent but when I clicked on the link and put in my email address as requested, the answer says that my email is not in the folder (!)

    Question: is there a live person I can talk to about it?
    My question: 1) my internet access definition had been changed, folder 2) microsoft says my email address is not registered.  The service ID was 1158399549ID SRX.  I think it is ridiculous that a SRX is sent to my email address and then says that it is not in the folder.  (3) when I asked for help and put in my product ID, message indicates the product is not taken in charge in the country, USA.  What is going on?  Where the product is supported then?

  • How can I identify the program that turns my internet access?

    Normal mode startup I get an IP address from my router but no internet access, cannot ping the router IP address or IP address of another computer on the local network.  I ping my own IP address.  I can access the internet if I start my computer in Safe Boot w/Internet.  I'm guessing that a program is power off or blocking the ability of network cards to talk beyond my computer during startup.  There are system variables, I can look at, or a list of programs that need to run, so that I can turn off others and test to see if the network works? This problem affects both my Wi-wired connections and my computer.  They both Act the same way.  I even installed a second adapter USB wireless as a test and it also reaches the router initially and then won't talk to her after the security negotiation.  McAffee software detects no virus on the system and no virus found or deleted in the previous analysis of the reports.  The problems started when I rebooted my machine to get the sound to work.   I had been running without the speakers connected and found the sound does not when I plugged.   The only known software update was of Flash Player, but I see no way out with a restore point, which is days of May and was generated from a Windows Update.  Everything worked fine after that Windows Update including the speakers.   I need help, or will be forced to recreate the image on my machine, I want to avoid.
