Cisco Wide Area Network

Cisco Wide Area Network

Situation:

The client, a business employing approx 60 users in the Telecommunications market with three sites nationwide, asked Signal Networks to develop a much more reliable network across all three of their sites. They already had a Cisco VPN in place between all sites but they were constantly having problems with slow access and dropped connections. Their email server was also in need of an update and they were keen to utilise all features available in Exchange 2003 for internal and remote users.

Requirements:

• Improve network access between sites.
• Provide better access for remote users to offices and email.
• Mobile access to company email.
• Upgrade Exchange 5.0 to Exchange 2003.

Resolution:

Once work had started an inspection carried out by Signal Networks discovered that the configuration on the Cisco routers and PIX firewalls contained many errors which were causing the WAN to become unstable. The Windows servers were also not configured for optimum WAN performance, replication between servers in the WAN also contained a number of errors.

Within days of working with Signal Networks the network was finally beginning to function as it should with an improved service throughout the WAN and data synchronisation functioning correctly.

Exchange server 2003 was installed at the head office with users in remote offices configured to access their mailboxes easily and securely via the VPN.

This greatly improved the company’s productivity and solved the delay of waiting long periods of time waiting for IT issues to be resolved.

A remote support contract with Signal Networks successfully resolved the problems the users were having.
