Unable to borrow license

[prem.savio]

AutoCAD Electrical 2015 & AutoCAD Mechanical 2015 are installed from the package PDSU 2015 on my computer. The software acquires the license from the server without any issues but when I try to borrow the license, the following error pops up. You cannot borrow a license at this time. Try again later. If this problem persists, contact your system administrator. Note: You can continue to use Autodesk Product Design Suite Ultimate 2015 while you are connected to the network license server. Error: [-5.414.0]

Do you know if there is an adskflex.opt options file that is preventing license borrowing from happening? 

[prem.savio]

Hi Travis, Thanks for replying. And no, there is no adskflex.opt options file in the license server.

If you want to PM me your debug.log file from your license manager, I will take a look at it for you.

There is an interesting development to the problem. I have shifted one of the PDSU licenses from the old server to my machine (my machine is both, the server and the client now and contains 1 PDSU license). The license seems to get borrowed from my machine (current server) but it results in -5.414.0 license error when I try to borrow the license from the old server. Does this mean, the problem is with the old server?

[TravisNave]

Possibly. If you want to provide me the debug log file of the old server, I
will look at it for you.

I recently encountered a similar problem, however, I am able to borrow a license for up to 161 days, and can't borrow for the maximum period. If I select the maximum period of 180 days, as limited by the product, i get the same [-5.414.0] Error.

I am using both Infrastructure and Prduct Design Suite Ultimate, running Windows 8.1

Hopefully you can help with this.
