connect Windows 8 client to Mac OS X Server Fileshare
It seems that your Windows 8 Client is using SMBv3 but your 10.9 Server is using SMBv2. There is a Tech-Note on the Microsoft-Support Site (see here) which suggests disabling the Security-Negotiation Settings, f.e. either manually set the required flag in the Registry:

"HKLM:\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters"

RequireSecureNegotiate -Value 0 -Force


or running the following command in the PowerShell:

Set-SmbClientConfiguration -RequireSecuritySignature $true
