Drawings Freezing on opening

[Anonymous]

Our whole office is unable to open drawings from the network for long periods of the day. Even when we copy the drawing to the computer it will not open.

Then suddenly for no reason at all it starts working for about an hour and then reverts back.

We have tried most the things we can find in related articles for example certifate revocation, reinstalling, reset profile. We have removed various windows updates that have being linked to simlar issues. The anti virus on our test machine has being removed also.

We changed the DNS settings on our test machine to 8.8.8.8 and 8.8.4.4

My hunch is that it is internet related but to be honest I am out of ideas hence me posting on here. I am willing to go through every step of any suggestion one by one.

We are currently working as we copy the files required and remove the network cable which allows us to work.

Autocad LT, versions 2014, 2015 and 2016 all affected.

Please help 🙂

Could it be something simpler, like your network switch is on the fritz?
What kind of "network" are we talking about?
Your files are on a server or appliance, or a cloud service?

There is nothing to fix inside the software, your issue is beyond your PC: hire a professional networking consultant in your town to come over and diagnose the problem and help fix it.

Hi,

We had a 100MB network when the issue first occured and the IT company we use sugested an upgrade to 1000MB so we did.

We had an improvement for some time but then on Friday it started again.

The internet works fine, files open fine on the wrest of the network. No latency.

Is there a list of ports, services and programs anywhere (I have spent a lot of time looking to no avail) that decribes what Autocad requires on the internet and the destinations it is trying to access?

I would agree that Network might be at fault if the program did work from a desktop machine but it is exactly the same until the network cable is removed. Which suggests it is certificate problems or name resoulution or even firewall prevention surely?

Correct: removing the nework forces your PC to stop looking outside of itself for resources and your problem goes away.

Contact your IT Company and ask them to come into your office: they still have a lot of work to do. This is not the place to fix networking issues.

Forgot to add: you can turn off AutoCAD/LT's Commctr, sign out of A360 and install/use only locally installed HELP file to reduce the software's need to tap the internet. But your networking issues will likely still be present.
