I have a problem that I am using a PC based DVR system the problem is that I have made an account for a user

and everything works right and I can access the dvr through the internet but after accessing it for about 5 or 6 times when I try to access it again with the username & password of the account it keeps on telling me that access denied wrong username or password and when I restart the PC everything works again but after few times it make the same problem Access Denied but I still can access the web client but I can't login.

 

The software I am using is UNISIGHT standard

I want only to share the solution of this problem I have partially solved the problem as the problem was with the registration file as the vendor I purchased from him the dvr card was giving me a wrong registration file and he will contact unisight I think for the registration and he will send it to me.
