Hey folks! I've been tasked by our organization to disable some outdated protocols like SMB1, RC4, and SSL 3, and enable SMB signing along with TLS 1.2 and 1.3. To do this, I ended up creating a registry file with ChatGPT's help to execute these changes in the Registry Editor. However, after applying the changes, we're experiencing some weird issues. Our computers can't see file sharing on the network, and I can't print because the printer, which is connected to another PC, is unreachable. Additionally, I'm having trouble connecting to the 1C application and the onlinesigner program. I've tried reversing some of the registry changes on certain PCs, and while one of the 1C programs started working, the other issues persisted. Could anyone provide suggestions on how to troubleshoot this? Are there specific PowerShell commands I should run? What do you think might have triggered these network and printer issues? Just to note, we're on a domain, but I made these changes individually on each PC—not through Group Policy. Any advice would be greatly appreciated!

First off, it's not a great idea to blindly apply changes from a tool like ChatGPT in a production environment. You should always test registry changes in a safe environment before deployment. Monolithic changes can complicate troubleshooting. I'd recommend disabling SSL3, TLS 1.0, and TLS 1.1 one at a time and testing after each change. For reference, IISCrypto is a fantastic tool for managing which ciphers and protocols are enabled. Make sure your SQL/ODBC drivers are compatible with TLS 1.2, as that might be causing some of your issues. You might want to check those drivers first before rolling back any of your changes.
Joining the test-the waters crew with registry changes, huh? Always a risky move! If you've got access, IISCrypto will let you see and adjust TLS settings effectively. If you're nervous about GPO due to permissions, definitely try working with individual machines first, but just remember to keep track of what you change. One-by-one changes lower the risk of widespread issues!
Totally! Changing them one at a time sounds much smarter. Appreciate your help!
Using PowerShell could help simplify some of this—though it sounds like you're new to that. Just remember, not everything generated automatically should be trusted. Always verify the commands first. If you're unsure about the specific commands, reach out or test safely before executing.
I’m a bit lost on PowerShell, but I’ll definitely look into it more. Thanks for the advice!
Thanks for the tip about IISCrypto! Should these changes be handled by sysadmins? Or can helpdesk staff like me do them too?
