Q: One of our networking printer shows out of paper. But it is not.

chicagotech.net: assuming the printer on the server also shows Out of paper, you may need to re-install it on the printer server.

Q: After restring my computer, I can’t login and access any network resources. However, other computer can’t login my computer using remote desktop with this message: “The specified network password is not correct”.

chicagotech.net: in this case, the password is computer password, which means the computer account in domain is crashed. If reset computer account in domain doesn’t fix the problem, try to disjoin the domain and re-join it.

Q: My windows 10 computer has some network problem and the network connection shows as “unauthenticated”. How do you fix this problem?

chicagotech.net: Some suttestions:

1. Run these commands on each computer with the problem: 1) netsh winsock reset catalog; 2) netsh int ipv4 reset reset.log; 3) netsh int ipv6 reset reset.log 4) Restart the PC then rejoin the computer to the domain.

2. One possible reason for this issue is when the machine account password gets out of sync with the domain controller. This can happen, for example, if the computer account in Active Directory is manually removed and re-added. What worked for me was to reset the machine account password by executing Reset-ComputerMachinePassword in an elevated(!) PowerShell: PS> Reset-ComputerMachinePassword -Credential MYDOMAIN\SomeDomainAdminAccount After rebooting, the (unauthenticated) note should be gone.

3. Run these commands Open ‘command prompt’ by searching it in the Windows search bar. Try the following command one by one and restart the system. Basically these commands – renew the IP address, reset Winsock, Flush DNS cache, and reset TCP/IP. •ipconfig /release •ipconfig /renew •netsh winsock reset •netsh int ip reset •ipconfig /flushdns •ipconfig /registerdns •netsh int tcp set heuristics disabled •netsh int tcp set global autotuninglevel=disabled •netsh int tcp set global rss=enabled •netsh int tcp show global.

4. Check DHCP and DNS for any problems.

5. We have the similar case. The problem is the machine was restored from system point. We must disjoin from domain and re-join the computer to the domain. That fixes the problem.

Q: When I use remote desktop to access desktop in the office, I received this message: “The specified network password is not correct”. The password is correct. Both machiens are running Windows 10. What could be the problem?

chicagotech.net: There are many people report the same problem. Try these:

1. Make sure both computers have correct time.
2. Disable the firewall/ anti-virus temporarily installed on your computer and then check if the issue still persists.
3. Make sure these services are set to automatic. i. Click start and type services.msc in the search box. ii. Check if the following services are started, if not start the service and set it to automatic. List of services: i. SSDP Discovery ii. TCP/IP NetBIOS Helper iii. Computer Browser iv. Server

Q: We are using Office 365. One of our users can’t send email to one of his clients with NDR 550 5.7.350. What could be the problem?

chicagotech.net: There are many causes for the NDR 550 5.7.350.

1. If this is only user in your organization has this problem, it is possible recipient block the user.
2. If the user can send email without attachment, it could the attachment issue.
3. If emails sent this client from everyone in your organization are rejected, it’s likely that only the recipient’s email admin can fix this problem. You may contact the recipient’s email admin and ask them to add your domain name, or the sender’s email address, to their list.of allowed senders

Q:

The user works at home PC and use Cisco VPN to connect to the office. he has a problem to map LAN shared folders over VPN. The error message is You do not have permissions to access \servername\foldername..

We have tried these:

1. It is not DNS issue because when we try IP address, we get the same problem.
2. Disable Symantec Endpoint Protection and Windows firewall for a test. But that doesn’t fix the problem.
3. Telnet ip address port 445, get timeout, meaning some thing blocks accessing.
4. Check “Control Panel\All Control Panel Items\Network and Sharing Center\Advanced sharing settings”. Make sure Network discovery is turn on.
5. Enable SBMV1 by going to Programs and Features.
6. The same user using other VPN client doesn’t have this issue.
7. Tried different domain admin account in his PC, have the same problem.

I think there is a security software blocking the map on the home computer. How can we find it? Is the SEP having some settings need to check?

Chicagotech.net: we fix this problem by adding a rule on Symantec Endpoint Protection. Please refer to this link: How to create a rule on Symantec Endpoint Protection

Q: I have a new Windows 10 computer. My DYMO LableWroter 450 doesn’t work. Or sometimes works. What could be the problem:

chicagotech.net: We are assuming the new computer comes with USB v3 and V2. Please try to connect the USB cable to USB v2. That fixes most problems.

Also check this statement from Dymo:
