Situation: the client is internal company and has migrated their multiple domains into a Microsoft Tenant. Now, they have an issue to send emails between domains. For example, A.com and B.com are under the same Tenant with default domain name C.com. Email sent from A to B was blocked.

Cause: They encountered this issue during the migration of A.com and B.com to C.me. Although I am not entirely certain about the reason, I have a theory. Both A.com and B.com are under the Microsoft Tenant. When A.com sends an email to B.com, Microsoft Intelligent Assistant (which is not as intelligent as a human) mistakenly identifies the email as spam and blocks it.

Resolution: Add A.com, and C.com to whitelist. Please refer to these posts:

Troubleshooting:

1. The user/group may not have access to LAN subnets. In our case, the client adds All Interface IP instead of LAN Subnets. We fix the problem by replacing All Interface IP with LAN Subnets.

2. The SSLVPN IP Pool is in the same subnet as X0.

 

If your computer display has these issues:

• A blank or black screen.
• Color fade.
• Fuzzy, blurry, distorted, stretched image.
• Geometric distortion.
• Light leakage or bleeding.
• Flickering.
• Horizontal or vertical lines.
• Light or dark patches.

Try these suggestions:

1. If you have two or more displays, compare them settings.
2. Check Display Settings by going to Advanced display and check the refresh rate.

 

 

Situation: The client try to access their SonicWALL Global VPN, but it shows Connecting forever.

Troubleshooting: It seems like Peer IP or name issue.

Go to Properties>Peers>, click on Edit.

Uncheck “Use the default gateway as the peer IP address”. Then enter the peer’s IP address, which should be the SonicWALL WAN IP address.
