Situation: When the client tries to map a file share, he receives the following errors:
•System error 53 has occurred. The network path was not found.
•System error 67 has occurred. The network name cannot be found.
•System error 87 has occurred. The parameter is incorrect.

Cause 1: Unencrypted communication channel

Windows 8, Windows Server 2012, and later versions of each system negotiate requests that include SMB 3.0, which supports encryption. If the communication channel isn’t encrypted and if the connection attempt isn’t made from the same datacenter where the Azure file shares reside, you may receive above errors.

Resolution: 1. make sure the communication channel is encrypted. Make sure your client OS needs support SMB 3.0, for example use Windows 8, Windows 10, Windows Server 2012.

2. Put the client in the same LAN.

3. Make sure the client computer network is domain or private. If it is public network, we may have a problem to access LAN shared drive.

4. It is not recommended, but you can try to enable SMB 1.0.

Cause 2: Port 445 is blocked

Resolution: you can use Portqry to query the TCP:445 endpoint. If the TCP:445 endpoint is displayed as filtered, the TCP port is blocked. Here is an example query:

c:\PortQry.exe -n [storage account name].file.core.windows.net -p TCP -e 445

If TCP port 445 is blocked by a rule along the network path, you will see the following output:

TCP port 445 (microsoft-ds service): FILTERED

Resolution: Work with your IT department to open port 445 outbound

Cause 3: NTLMv1 is enabled

System error 53 or system error 87 can occur if NTLMv1 communication is enabled on the client. Windows new version Files supports only NTLMv2 authentication.

Resolution: To determine whether this is the cause of the error, verify that the following registry subkey is set to a value of 3:

HKLM\SYSTEM\CurrentControlSet\Control\Lsa > LmCompatibilityLevel

Resolution: Revert the LmCompatibilityLevel value to the default value of 3 in the following registry subkey:

HKLM\SYSTEM\CurrentControlSet\Control\Lsa

Situation: The user just changed his domain login password. After that he can’t make phone call.

Troubleshooting: Logoff Shoretel Connector and re-login.

Situation: after enabling Azure Multi-factor authentication, the client can’t login his Office 365 account. For example, the Word shows the username with yellow or sign in. When he tries to login and select work or school, the window disappears.

Troubleshooting: 1. Run Office repair.

2. Run Credentials Manager. Click on Windows Credentials. Remove all office 365 related credentials.

3. Run Settings>Home>Accounts. Click on Access work or school. If you don’t see Office 365 account, click Connect. If you do see the office 365 account, disconnect it. Then re-connect.

Situation: the user is using Outlook 2016. She opens Outlook this morning and gets this message: cannot start Microsoft outlook. cannot open the Outlook window. The set of folders cannot be opened. the information store could not be opened.

Troubleshooting: Repairing Outlook doesn’t fix the problem. We have to remove and re-add Outlook profile.

Q: After we use group policy to add url to IE local interanet zone , users can’t add others url by themselves. Why? We want to use group policy to URL and the users can’t remove, but they can add some URL by themselves.

Situation: The client has a problem with the office Excel. If the mouse is hand sign, it works fine. Sometimes, it changes to + sign and she can’t save the file.

Troubleshooting: run Office repair.

Situation: The user gets a new Computer with Office 2016. However, whenever she try to change the Signature from Outlook options, the Outlook freezes.

Troubleshooting: run Office repair.

Situation: the client receives a Gmail a security warning and followed the instruction to change the security settings for Gmail. After that he can’t access Gmail in his Outlook and it keeps saying “incorrect password”.
