Many users were unable to install Telnet by using the control panel method and this worked for them. You can also install Telnet by using a single command in command prompt. Method 2: Installing Telnet through Command Prompt in Windows Now go try the Telnet command again in command prompt.Find Telnet Client in the list and tick it to install, then click OK.Opening Turn Windows features on or off option Click on Turn Windows feature on or off in the left bar.Hold Windows key and Press R to open Run, then type “ appwiz.cpl” and Enter.However, it is really easy to enable it from the control panel on your system by following the steps below: Telnet is disabled by default in Windows. Some of the features are disabled on Windows because it will slow down the performance of the system. Here is discussion on routers, SSL and Windows 8.Method 1: Enabling the Telnet Executable in Windows This is more related a transport/authentication issue.Ĭonnecting to a hosted 2010 exchange server.Īuthentication (this is for sharepoint but it talks about your config file).
#TELNET SERVER WINDOWS 8.1 CODE#
It is unlikely that this is a Application coding problem considering the code works on some Windows 8 machines with SMTP and older versions of client server setups. Reason seems to be due to the base 64 encryption not being able decrypt on your SMTP server. So then you would look for your host settings somewhere and configure it there. If you are using 3.5 or 3 it won't work in config.

See if you can set SMTPEnableSSL=N or false in your web config settings. More client related but along the same lines to try to avoid bumping the 64base encrypt/decrypting problem.Here is a work around attempt from the client side which is basically rendering SSL auth useless (leaving this just to illustrate that people are attempting to approach this from the client side). Windows 8 is throwing something at it and Exchange folds because of interpretation problems. I am seeing a lot of the 64 base interpretation on various different things pointing to a backwards compatibility issue on your exchange server. So the Exchange Server had to have something modified. I have fetched that information and brought it back:Ĭreate a new CSR on the Exchange server and reissue the certificateĪnd review this post where a base64 was request to exchange but failed. But then again it just might be the right way to go after all. (but then changed my approach to the client to see what could be done there since it seemed like Weekend changes server-side would have a lower probability. Keep reading!īefore I changed my answer I was pointing to the Exchange server as the problem. This could be related to this bug: but this is just with the subject header and not authentication.

Update 4: EnableSSL=true does not fix it. This is similar to my Telnet Login experience. The difference between SendGrid and my Hosted Exchange is that SendGrid only supports I tried using SendGrid and it works fine on Windows 8.x machines. The Windows 8 machine sends something like this: C: AUTH gssapi Token Signing Public KeyWELLKNOWN:

The Windows 7 machine sends something like this: C: AUTH gssapi NTLMSSP + some encoded chars.

I compared the Wireshark output from a Windows 8.1 machine and a Windows 7 machine (where everything works fine): S: 250 Hello | 250 SIZE 104857600 | 250 PIPELINING | 250 DSN | 250 ENHANCEDSTATUSCODES | 250 STARTTLS | 250 AUTH GSSAPI NTLM LOGIN | 250 8BITMIME | 250 BINARYMIME | 250 CHUNKING Here comes the WireShark SMTP Log: C: EHLO Sending the mail using Windows telnet client works without any problems also. Setting defaultCredentials to true or false also doesn't matter. It doesn't matter whether the code runs in an IIS or Console Application.

Running the same code on a Windows Server 2008 R2, Windows Server 2012 or Windows 7 works as expected…Īm I missing same magic on Windows 8.1 machines? Message.From = new = "This is my subject" Īgainst a hosted Exchange Server results in several issues like 5.7.1 SMTP errors (not authenticated, base64 required etc.) Running this piece of code: var message = new MailMessage() I’m facing the following issue on multiple (not to say: all) Windows 8.x machines:
