Our client needed to take advantage of new features and higher mailbox size limits in Microsoft Exchange 2013. EMKAL migrated over 50 active mailboxes and public folders from Exchange 2007 to Exchange 2013 with no downtime to Outlook, OWA, ActiveSync, or SMTP. In addition to meeting their current demands, the client is now ready to create a hybrid deployment with Office 365, and embrace the cloud.
We were referred to a client whose mail server was bouncing back messages from the British Columbia Ministry of the Environment. Their existing IT service provider was unable to identify the root cause. We initiated contact with the client, gained access to their systems and services, diagnosed incorrect MX and nameserver records in DNS, and had the solution implemented in less than 48 hours.
Our client's Paypal IPN integration built on the ColdFusion platform suddenly stopped processing orders and the client's programmer could not identify the root issue. We began by inserting debugging statements and traced the execution of the application right down to the line causing the error. We discovered that the hosting provider was using an out-of-date Java certificate store causing SSL negotiation to fail. We worked closely with the provider to release the backlog and restore the online ordering system.
Our client was experiencing slow access to their main application server. Using a combination of Windows Resource Monitor and Atto Bench32, we identified the root cause as poor disk performance. We discovered the RAID adapter for the HP DL360 server did not ship with a Flash Backed Write Cache (FBWC) module and 3 of the 5 installed disks were not in use. We sourced and installed the cache module, then flashed the server firmware before performing a live migration from RAID 1 to RAID 1+0 (plus hot-spare). The result was 20x faster disk performance from the same hardware.
A client with an aging infrastructure depended on a single workstation running Windows 2000 for Workplace Hazardous Materials Information System (WHIMS) label printing. We developed custom software, using ASP.Net on IIS, to generate and print labels using the latest version of Windows Server. Migrating to a Virtual server and enabling multi-tenant access to the printers eliminated the single point of failure and increased operating efficiency.
