resolving hostname faild, but only when ther is a minus hyphen ('-') in the hostname
for example when i try to access host SERVER1:
resolving host by name: SERVER1
resolved: SERVER1(192.168.0.82)
connecting to 192.168.0.82:5900
for example when i try to access host IT-PC1:
resolving host by name: IT
failed to resolve locally
for example when i try to access host FIBU-PC2:
resolving host by name: FIBU
failed to resolve locally
same problem when i try the FQDN with a Minus
for example when i try to access host PC1.MY-COMP.LOCAL:
resolving host by name: PC1.MY
failed to resolve locally
so the problem is, the Minus and every thing after the Minus, will be Cut off
i have also tryed 'IT-PC1' and "IT-PC1" but does not work.

when i make an Alias in the DNS IT_PC1 => IT-PC1 it works with IT_PC1
but this is rearly not what i like to do for all clients.
any ideas

a Minus in a hostname is RFC conform:

Restrictions on valid host names
The Internet standards (Request for Comments) for protocols mandate that component hostname labels may contain only the ASCII letters 'a' through 'z' (in a case-insensitive manner), the digits '0' through '9', and the hyphen ('-'). The original specification of hostnames in RFC 952, mandated that labels could not start with a digit or with a hyphen, and must not end with a hyphen. However, a subsequent specification (RFC 1123) permitted hostname labels to start with digits. No other symbols, punctuation characters, or white space are permitted.
