I am using the following to send a text message

objIntelliSMS.PrimaryGateway = "https://www.intellisoftware.co.uk"
        objIntelliSMS.BackupGateway = "https://www.intellisoftware2.co.uk"

        objIntelliSMS.ProxyAddress = "**********"
        'HttpWebRequest.DefaultWebProxy.ToString()
  
        objIntelliSMS.ProxyUsername = "***************"
        objIntelliSMS.ProxyPassword = "***********"

        mobNo = mobNo.TrimStart("0")
        mobNo = "44" + mobNo

        objIntelliSMS.Username = "***********"
        objIntelliSMS.Password = "**********"

        Try
            MessageId = objIntelliSMS.SendMsg(mobNo, sms_message, "**********")
            SendTxt = MessageId
        Catch smsExeception As IntelliSMSException
            SendTxt = "SMS Error Type: " + smsExeception.ResultCode.ToString + " " + smsExeception.Message + vbCr + smsExeception.InnerException.ToString
        Catch ex As Exception
            SendTxt = ex.ToString
        End Try

I am getting a the following error:

We have not heard of this issue before.

Looking around the internet there are plenty of references to this error you have encountered:
Request for the permission of type 'System.Net.WebPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

It appears to be an issue with the trust level of our IntelliSMSDotNet.DLL assembly. It is probably run with Medium trust level.

A work around is to edit the C:\WINDOWS\Microsoft.NET\Framework\vx.x.xxxx\CONFIG\web_mediumtrust.config file.

Add the following URL to the IPermission node for class="WebPermission":

<IPermission
    class="WebPermission"
    version="1">
        <ConnectAccess>
            <URI uri="$OriginHost$"/>
            <URI uri="http://www\.intellisoftware\.co\.uk/smsgateway/.*"/>
            <URI uri="http://www\.intellisoftware2\.co\.uk/smsgateway/.*"/>
            <URI uri="https://www\.intellisoftware\.co\.uk/smsgateway/.*"/>
            <URI uri="https://www\.intellisoftware2\.co\.uk/smsgateway/.*"/>
        </ConnectAccess>
</IPermission>

After the code change you will need to restart you IIS (or alternative reboot your machine)

I have made the change to the web_mediumtrust.config in C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\CONFIG (which is the only web_mediumtrust.config file i could find) and I am still getting the same error.

Seems that .NET relies on the full trust permissions that the My Computer one has.

So I have moved the application to the C: and its working fine.

Thank you for you speedy reply.
