Situation: The client replaced their SQL server with a new server and keep the same name and IP. They deleted the old server backup from the Barracuda and create the new backup. The backup gives this error:

Microsoft SQL

        LocalServer/AutoEmail – Unable to perform differential backup: an external program has made a full backup of this database. Please run a full backup before attempting another differential backup.

Troubleshooting: Since this is the new server replacing the old one. you need to do full backup at the first time.

Go to Backup>Schedules. Fine the server and click Edit. In SQL/Exchange Backup, switch the Smart to Full, After the backup success, switch the Full back to Smart.

Situation: The client just have a new Sharp Printer MX-M1055. When they try to import Address book from Sharp MX-6070N, they get this error: “ERROR[3514]: Processing failed. The file/folder cannot be imported.”

Troubleshooting: we may not be able to import some model printer address book.

Situation: The client just replace their Canon printer with Sharp Printer with the same IP address. They can ping it, but can’t access from web browser.

Troubleshooting: checking the network settings, we find they entered incorrect subnet. It should be class B 255.255.0.0. But they entered class C 255.255.255.0. Correcting subnet fixes the problem.

A. Troubleshooting AD and DNS Tools

1. Active Directory Replication Status Tool – check this post for how to use AD Replication Status Tool.

Situation: The client move their FTP server from Windows IIS/FTP to Syncplify.me FTP. Some clients have a problem to upload files.

Troubleshooting: 1. Paloalto Firewall monitor shows the FTP was established without any issues.

2. FTP log shows:

2019-10-31 19:40:53 69.x.x.x ftptransfer 10.0.0.2 21 PORT 69,x,x,x,221,201 – 200 34 28 – W7WVJ6DPADUJJOYYJ2ZW2SLLI FTP –

+FTPServerClose

This client is trying to connect using ACTIVE FTP… basic knowledge of the FTP protocol would suffice to determine that this would never work. When a router or a firewall is between the client and the FTP server, the ONLY type of FTP that could ever hope to work is PASSIVE FTP.

So the client must be reconfigured to use PASSIVE FTP.

and make sure the server site firewall should open range ports, for example 1024-65536.

Note: the client site doesn’t need to open any inbound ports. However, if they blocks any inbound and outgoing ports, that will be a problem.

Update:The web server needs to be configured to send its external address as shown below.

Situation: Whenever the user opens Microsoft Edge, the small size is fine. However, if you Maximize, the windows shows only half.

Troubleshooting: 1. Reset display doesn’t fix the problem.

2. Right click on Microsoft Edge>App, reset or repair don’t fix the problem.

3. We also find some Windows applications such as Control Panel have the same problem.

4. We fix the problem by upgrade the display driver.

5. It happens again. I fixed it by upgrading the Monitor driver.
