i’ve recently removed a Buffalo LinkStation Network Harddisk in exchange of a W2K Server to support backup operations and datasharing. When accessing the data indendently the response time is fast – 1GB. However, when accessing the data through outlook it takes time to attach the file. Before the replacement of HD and Server this problem didnot exist. I found if I put the Linkstation HD back on the Network the speed is very quick to attached the files. There are 4 WXP Clients on the Network and 1 W2K Member Server. A Linksys router supplying DHCP. All clients are DHCP. Internet and other operations are working fine. Its only when I try to attached the file through outlook. Thanks for all replies.
