I have two NAS200's - aside from each using RAID 1 - mirroring - I use VicaVersa to copy from one to the 2nd - was working great until yesterday. The 2nd NAS 200 unit (copy recipient) will not allow me to attach a drive to the PUBLIC DISK data. I can ping it and I can admin it via IE (though its VERY slow). I was going to try a firmware update perhaps - anyone see this behavior before? Both units were DHCP - I went static - but same issue (I was just trying to eliminate any variables). I can ping by name or IP - tried Explorer mapping and a NET USE * "\\NAS2\PUBLIC DISK" but neither are working - out of the blue! Any suggestions greatly appreciated.
