For Lund, owner of Lund Computer Services, Northglenn, Colo., the decision was made when he walked into a client's site for the fourth time in a month after its Exchange server had gone down again. "Every time I'd go in, I'd feel these dirty looks from [employees]. It was one of our biggest customers and it was costing them a ton of money to maintain Exchange," he said.

Hoague, owner of Network Dynamix in Greenwood Village, Colo., was experiencing similar angst with clients. The two solution providers began to share their experiences. And then Lund stumbled across an alternative e-mail vendor, Kerio, on an Apple (NSDQ:AAPL) forum and decided he and Hoague needed to take a closer look. "Within an hour, we had a full-blown server on Linux up and running. An hour. With mail, calendar, tasks. It blew us away," said Hoague.

The pair deployed Kerio in their own respective solution provider companies and liked it so much they decided to collaborate on a new joint venture focusing exclusively on Kerio solutions. Three years later, that venture, OnePointSync, is so successful that both are looking to wean themselves out of their respective solution provider businesses to focus full time on OnePointSync.
