Yesterday we tested all the systems and only one system can able to access our servers at a time (sometimes when both LAN on one system and Wireless on another system connected, it giving priority to Wireless).
The problem seems to be like the server is not allowing concurrent connections from same IP Address( our IP Address is 87.194.169.12

.
All other websites and internet is working except our websites, Outlook, webmail like businesstransformation.co, businesstransformation.co/crm, businesstransformation.co/expo, businesstransformation.co/awards so so……
Please make sure the server should able to allow concurrent connections from Same IP address;
We have here 10 systems (7 laps and 3 desktops; laps are connected via Wireless and Desktops are connected via LAN)
Please let me know is there any restrictions on this IP, so that the server not able to send response to all systems using this IP;
Thanks
