Gmail rejecting exchange 2010 2013 emails with: The sender does not meet basic ipv6 sending guidelines of authentication and rdns resolution of sending ip.

Issue:

gmail.com is rejecting emails from Microsoft Exchange 2010 and Microsoft Exchange 2013 email servers for no PTR records even if you do not have any IPv6 IPs assigned to the server.

 

Error:

The sender does not meet basic ipv6 sending guidelines of authentication and rdns resolution of sending ip. Please review https://support.google.com/mail/answer/81126for more information.

Your message wasn't delivered due to a permission or security issue. It may have been rejected by a moderator, the address may only accept email from certain senders, or another restriction may be preventing delivery.

mx.google.com #550-5.7.1 [ipv6info] The sender does not meet basic 550-5.7.1 ipv6 sending guidelines of authentication and rdns resolution of 550-5.7.1 sending ip. Please review 550 5.7.1 https://support.google.com/mail/answer/81126 for more information.

 

Solution:

Disable certain IPv6 components yourself, follow these steps:

  1. Use the registry editor to edit the following path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\
    • Edit or create DWORD (32-bit) value "DisabledComponents".
    • Default value is "0", you will need to change this to "0xffffffff"(Hexadecimal "ffffffff" or Decimal "4294967295") in order to disable all IPV6 other than local loopback.
  2. Verify that IPV6 is disabled with the following command: "reg query HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters /v DisabledComponents"
    • You may receive the following error message: "ERROR: The system was unable to find the specified registry key or value."
    • If you receive this error message, the DisabledComponents registry value is not set. If the DisabledComponents value is set, it overrides the settings in the connection properties.

Solution 2:

If you have IPv6 IP's enabled on the server verify that your PTR records are correctly setup.

Exchange 2010 / 2013 Powershell Error: A specified logon session does not exist. It may already have been terminated.

Error: Exchange 2013 Failed to connect to an Exchange Server in the current site. Anyone ever run into this with exchange 2013 enterprise AD and exchange are separate servers.

I checked firewall, reinstalled .net, reset IIS, etc... really stumped on this one.


Error:
New-PSSession : [exchangeserver.domain] Connecting to remote server exchangeserver.domain failed with the following error
message : WinRM cannot process the request. The following error with errorcode 0x8009030e occurred while using
Kerberos authentication: A specified logon session does not exist. It may already have been terminated.
Possible causes are:
-The user name or password specified are invalid.
-Kerberos is used when no authentication method and no user name are specified.
-Kerberos accepts domain user names, but not local user names.
-The Service Principal Name (SPN) for the remote computer name and port does not exist.
-The client and remote computers are in different domains and there is no trust between the two domains.
After checking for the above issues, try the following:
-Check the Event Viewer for events related to authentication.
-Change the authentication method; add the destination computer to the WinRM TrustedHosts configuration setting or
use HTTPS transport.
Note that computers in the TrustedHosts list might not be authenticated.
-For more information about WinRM configuration, run the following command: winrm help config. For more
information, see the about_Remote_Troubleshooting Help topic.

Microsoft SQL Server Management Studio Maintenance Plans error: 'Agent XPs' componet is turned off

If you did not set the ..

Full Error:

'Agent XPs' component is turned off as part of the security configuration for this server. A system administrator can enable the use of 'Agent XPs' by using sp_configure. For more information about enabling 'Agent XPs' see "Surface Area Configuration" in SQL Server Books Online. (Object Explorer)

Fix Options:

  1. if using GUI open services, locate SQL Server Agent, double click and set startup type to automatic then click start.
  2. if you prefer to use command line you can just do the following on the master database:
    EXEC sp_configure 'show advanced', 1; 
     RECONFIGURE; 
     EXEC sp_configure 'allow updates', 0; 
     RECONFIGURE; 
     EXEC sp_configure 'Agent XPs', 1; 
    RECONFIGURE; 
    GO

HTC ONE (M7) back and home button issues, work intermittently

Several solutions exist because their can be several causes to this issue:

  1. recalibrate your keyboard, be sure not to touch close to the back or home keys. To do this touch and hold the "," key while the keyboard is open then go to Advanced and click the calibration option.
  2. Do a software update
  3. Turn off the power save mode
  4. Make sure the screen cover is not covering the back ad home buttons.

If none of these work call HTC and get a replacement.
