Situation: The client has been running a new Veeam backup version 11 for one week. Now, the Veeam Backup has this Error: The user name or password is incorrect. Failed to process [isFileExists].

Troubleshooting: When we test it by mapping the NAS share folder, we also get this message: This share requires the obsolete SMB1 protocol, which is unsafe and could expose your system to attack. Your system requires SMB2 or higher.

We fix the problem by increasing SMB version from SMB 1 to SMB 2 on QNAP NAS.

Situation: The client has a problem to run Veeam backup with this error: “The user name or password is incorrect”

Resolution 1: Make sure use the correct username to access backup storage, for example NAS\username.

Resolution 2: The client just join the NAS to their domain, they need to access the NAS using domainname\username.

Resolution 3: Force the credentials renew in Veeam DB. Please follow this post: How to force the credentials renew in Veeam DB

Resolution 4: Run rescan on Repository by going to Backup Infrastructure.

Resolution 5: Remove the Backup reposition you don’t use it. 

Situation: The client reports two servers on their Hyper-V Host have a problem. Symptom: 1) The Veeam backup doesn’t work or backing up is every slow. 2) These servers are very slow. 3) We have a problem to access these two servers remotely. 4) Process in these two servers are very slow. Problem: there is a Windows update installed automatically and requires restart.

Troubleshooting: WE find the Host has Windows update installed and requires restart. Restating the Host fixes the problem.

Situation: The client has some servers on AWS which connecting to the LAN over site to site VPN. Today, two of servers on AWS can’t access one of LAN servers.

Troubleshooting: 1. Ping LAN server IP doesn’t work.

2. Paloalto firewall Monitor shows sending is fine. However, Packet received is 0.

3. AWS support confirm they don’t block access the LAN.

4. Finally, we find the server has a security software that blocks the AWS servers. Unblocking fixes the problem.

Situation: The client uses Malwarebytes cloud. Malwarebytes shows some computers need scan. They would like to know how to fix it. Resolution 1:

Make sure Malwarebytes services are running.

1. Type services on search bar. Then click Open.

2) Make sure both Malwarebytes services are running. If not, please start them.

Resolution 2: If there is a Windows Update holding, please install and restart the computer.

Resolution 3: Re-install the Malwarebytes agent.

Situation: The client setup Windows update to be checked only.

However, sometimes, the Update installs automatically and requires to restart.

Passible cause: After some Windows updates, the Settings change to the default: Install update automatically (recommended).

Situation: The client use DHCP Reservation to assignee IP address to each printer. Today, one of their printers (HP M608) doesn’t work. Can’t ping it by IP also.

Troubleshooting: 1. The DHCP Reservation shows correct configuration and the printer should be assigned 10.0.220.12.

However, printing configuration page shows the IP address is 10.0.200.44.

2. Double-check the hostname and Mac address are correct.

3. We fix the problem by changing to Statics IP address still using 10.0.220.12.

Situation: The client has PA-850 firewall running GloableProtect for VPN connection. After they changed the DNS by going to Network>Gloableprotect>Gateway>Agent and then Network services,

Some VPN client take the change but not all. Some users still use the old DNS server.

Troubleshooting: You also need to change the DNS server under Client Settings>Network Services.
